Server IP Addresses

Return to: Technical Information
UO Servers
By Petra Fyde, October 2011 From information supplied by Lord Obsidian and S.P.A

Since the hardware migration made in February 2011, all 28 Shards have been tied to new IP addresses. The “” DNS names are now redundant, though still in existence. Any application using those will return false and irrelevant results.

Each Shard consists out of 5* IPs: 1 main IP which is the one being pingable/traceable, and 4 IPs you will be actually connected to. However, the latter are not pingable.

The old subserver scheme, which broke Britannia into different areas having different IPs, is no longer valid. You will now be randomly connected to one of the 4 nonpingable IPs each time you log in, regardless where your char is located within the game’s world.

To ping (ping x.x.x.x) or get a trace route displayed (tracert x.x.x.x), please use the following IP addresses to get a meaningful result:
(For shards with ICMP Ping disabled, tracert will show the route up to the second last hop; ping will result in no answer at all.)

UO Trace

These server addresses can be used with the program UO Trace to help identify connectivity problems causing lag. The following information has been adapted from the EA Support document . To use the program:

  1. Create a file named SERVER.cfg in notepad (select ‘all files’, do not add .txt suffix), save it in the uotrace directory. Paste the following list into it and save the file:
    0=Arirang (,0
    1=Asuka (,0
    2=Atlantic (,0
    3=Baja (,0
    4=Balhae (,0
    5=Catskills (,0
    6=Chesapeake (,0
    7=Drachenfels (,0
    8=Europa (,0
    9=Formosa (,0
    10=Great Lakes (,0
    11=Hokuto (,0
    12=Izumo (,0
    13=Lake Austin (,0
    14=Lake Superior (,0
    15=Legends (,0
    16=Mizuho (,0
    17=Mugen (,0
    18=Napa Valley (,0
    19=Oceania (,0
    20=Origin (,0
    21=Pacific (,0
    22=Sakura (,0
    23=Siege Perilous (,0
    24=Sonoma (,0
    25=Test Center 1 (,0
    26=Wakoku (,0
    27=Yamato (,0
  2. Double-click on the uotrace.exe to run it.
  3. You will be asked if you wish to download the server list.
    Answer No to the question. (you have already created the list)
  4. Click on the Options menu then select Advanced.
  5. Select the server you wish to trace to from the drop down list
  6. Click on the Trace Route button. A succession of host names will begin to appear in the main window. These are the computers your data passes through on its way to the UO Server. Once the function is complete, a message that says Traceroute successful will appear in the lower left corner of the window.
  7. If you get a message saying Maximum number of hops exceeded:
    1. Click on Options
    2. Then click on Settings
    3. Change the max hops to a higher number and re-trace.
    4. N.B. This will always be the result for shards with ICMP Ping disabled, ip address shown in red.
  8. To the left of each host name there is a shield icon. These should be green, indicating no problems.
  9. Select the Poll button. This tells the program to send packets of data through the route to the final host. As the data is being sent, look at the “pkts r/s” column. Let it send about 40 packets then select Stop Poll.

How to interpret the results:

Host names/servers – These are the individual computers that make up the Internet. The connection you make to the UO server may travel through 15-25 individual hosts before reaching it. Problems suffered by these hosts can cause poor game performance. The shield icons next to the host names give a graphical display of quality. Green indicating a good connection and as it worsens, the colors pass through various shades of yellow, red, gray, and finally, black.

Ping Average – Ultima Online uses the TCP/IP protocol that sends data in the form of packets. A ping time is the amount of time it takes for a packet of data to be sent from your computer to a host server.
If you are getting pings that are higher than 200ms then you will notice a bit of latency in the game.
If the ping for a particular host is too high (above 225ms) it usually signifies that the host you are testing is either receiving more traffic than it can effectively handle, or is having some type of technical issue.

A high ping will cause your client to not be able to communicate fast enough with the server for the game to maintain fluid motion. This will result in your character’s movements appearing jerky and you will notice that the players and monsters around you seem to be able to move much faster than you can. This is due to the fact that the other players are most likely taking a different route to the server and are not being affected by the problem.

If you consistently notice high ping times, contact your ISP and discuss the problem with them. Be sure to have a list of the problem hosts or to actually be running UOtrace while you are speaking with them.

There will be some routers that your data will pass through that are independent companies and your ISP may not have any influence over them. In this case you can use the nifty Who is? feature of UOtrace.

Simply right-click on a host name
Select Who is?
You will be given information about that hop, usually including an email address and telephone numbers which you can use to contact them yourself.

% Loss – This is the percentage of packets that are being lost. In other words, you are sending information to or through that host and the host is either not receiving the data or is not able to return it to you. Any packet loss is a sign of some type of problem. These problems could be caused by hardware issues at the host server, bottlenecking (too many users communicating through that host), telephone line noise, and other causes.

Most packet loss issues are generally resolved quickly by the hosts (a matter of minutes), although some may take several days to resolve. If you consistently notice packet loss, you should contact your provider to discuss possible solutions. You may also consider trying a different ISP.

If you need to send the results of your UO Trace to EA’s Technical Support department, you’ll first want to save your results.

Click on the UO Trace Edit menu and choose Copy.
Open the NOTEPAD application.
Click on the NOTEPAD Edit menu and choose Paste.
Click on the NOTEPAD File menu and choose Save.
Click the Desktop icon on the left side, or choose another location to save the results.
Name your file appropriately, such as UOTrace-Results.txt.

These are the ‘stories’ behind the names of the various shards
Shard name Origin
Abyss The infernal regions of ancient Greek mythology. The name was originally used for the deepest region of the world, the lower of the two parts of the underworld, where the gods locked up their enemies. It gradually came to mean the entire underworld. As such it was the opposite of Elysium, where happy souls lived after death.Name of a MUD (Multi User Dungeon).
Arirang ‘Arirang’ is the name of a well known Korean folk song. Another name for the song is ‘Harangi Arirang’. Many people (especially high school band/orchestra players) would recognize it as the intro theme to ‘Variations of a Korean Folk Song’, written by Mr. Chance (I don’t remember the first name) ASCAP. If any of you have played the video game ‘Soul Blade’, then you might also recognize it as the name of one of the fighting stages (where I believe the harmony of the folk song is played in the background…)
Asuka Significant historical erain Japan – early 6th Century.

– Woman’s name.

– Asuka is a city in the northern region of Japan about 60 miles west of Sendai.

– Today the term “Asuka” commonly refers to a broad area centering around present-day Asuka-mura, but including parts of Kashihara-shi, Sakurai-shi, Takatori-cho, etc. However, in the 7th and 8th centuries, “Asuka” was used primarily in reference to the area bounded on the west by the Asuka River, bounded on the north by Mount Kagu (Kaguyama), and having its southern boundary in the vicinity of the Tachibanadera. The more northerly area of the Fujiwara capital and also the present-day districts of Toyura. Hinokuma, etc. (within Asuka-mura) seem not at that time to have been included in the designation “Asuka.”
Atlantic Close to the Atlantic ocean.
Baja A peninsula in California, Mexico
Baekdu A mountain in North Korea. Baekdu was an experimental shard, located in Korea and prepared exclusively for use in Korean internet game rooms (or “IGRs”). It was allowed to run for a predetermined number of months for testing, after which it was decided to not pursue that variation on the UO service.
Balhae The name “Balhae” was voted for by Korean Ultima Online players and dates from the country’s rich history as the title of a 7th century dynasty.
Catskills A mountain range located 2 1/2 hours north of the New York City metropolitan area and about 3 1/2 hours west of Boston.
Chesapeake A bay in Maryland (on the East coast).
Drachenfels Drachenfels refers to a place on the rhine near of Worms in germany. It is the place where Siegfried slayed Fafnir the dragon using the magical sword Balmung and a cloak who granted invisibility. Siegfried bathed in the blood of Fafnir, thus becoming incredibly strong, agile and invulnerable except for one spot on his left shoulder where an ahorn leaf covered his skin (it showed as a tattoo in form of an ahorn leaf). With slaying Fafnir Siegfried obtained the Nibelungen hoard, including the magical ring Andvaranaut which seeks out gold but was hexed by Andvari into giving all his bearers bad luck and pain. The posession of the ring leads to the tragic event when his brother-in-law Hagen murders Siegfried after pain and misfortune wrecked havock upon Siegfrieds family.
Europa Europa was the daughter of Agenor, and was beloved by Zeus. Zeus took the form of a beautiful white bull and encountered Europa at the seashore. By appearing to be very tame, he coaxed her to climb onto his back and then swam off with her across the sea to Crete. In Crete, Europa had three sons by Zeus — Minos, Sarpedon, and Rhadamanthys. Zeus also gave her three gifts: the bronze man, Talos, to act as her guardian; a dog, Laelaps, which never failed of its quarry; and a javelin which never missed its mark. Europa afterwards married Asterius, the king of Crete.
Formosa The name “Formosa” is an old name for the island country of Taiwan and dates back to the 1500’s when Portuguese explorers discovered the island. This discovery opened the doors for trade with the Western world; an economic tradition which has continued over the past 500 years. Formosa means “the beautiful” in Portuguese.
Great Lakes A group of 5 lakes. The Great Lakes-Big Rivers Region includes the states of Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Ohio, Ontario and Wisconsin.
Hokuto The “Great Bear” constellation. Hokuto Sheisei = north star.
Izumo Izumo is an existing Japanese city with a deep historical background and is also famous for the foreword thinking municipal programs that have been adopted lately. Many Japanese are familiar with this city, and with Izumo-taisha, which is an old Japanese shrine that imparts good luck for finding your mate. The city boasts a history rich with legendary stories and a culture from which many medieval samurais came. The Japanese characters for this name mean “cloud is out” or “coming out of cloud.”
Lake Austin Launched at the time of the 5th Year Anniversary in 2002. It is named after the twenty-two mile long body of water in Central Texas that runs right past the place where UO was born, the home office of Origin Systems.
Lake Superior One of the 5 lakes in the Great Lakes area. The other 4 are Lake Michigan, Lake Huron, Lake Erie and Lake Ontario.
Legends Opened originally in 2000 as AOL Legends shard, it was the only Ultima Online shard available exclusively through the America Online service. Initially called AOL Sosaria, but later renamed to AOL Legends in honor of Legends of Kesmai, one of the forerunners in the online role-playing game industry. In 2003 it was again renamed, losing the AOL name and exclusivity and opening its doors to all players worldwide.
Mizuho The name Mizuho dates from ancient times, when Japan was called “Land of Mizuho”. Mizuho stands for beautiful water, and Japan has been long famous for its rich rice harvest. The shard name was chosen from submissions to the official UO Japanese website and voted on by UO players via the website
Napa Valley A large wine producing valley in California not far from the Sonoma region.
Oceania Named for the approximately 25,000 islands located in the area of the Pacific Ocean known as the South Seas.
Origin Launched in December 2004 this shard is the first to receive new publishes. Named for the birthplace of the game, Origin Systems.
Pacific Close to the Pacific ocean.
Sakura The name Sakura is borrowed from the national flower of Japan, where Sakura trees boast beautiful blossoms during springtime.
Siege Perilous Siège means seat in French (note the accent over the first e)… so in fact the Siège Perilous means “Perilous Seat”.Also the name of the first moongate the traveler from time and space (later known as the Avatar) used to enter Sosaria was called Siege Perilous in Ultima lore. (Ultima 1)In Arthurian legend this was the name given to the one seat made from stone that for many years was left empty at the Round Table. Malory tells us that it was made by Merlin (II, 907 in Vinaver’s ed.).
It was said that only a Knight pure enough to search for and find the Grail could take this seat. The first in Arthurian legend was Perceval and then in later legends Galahad who became known as a Grail Knight deemed worthy enough to sit in it when both embarked upon the Siege Perilous. The siege perilous was much revered and believed that it would crack if anyone not worthy of sitting in it tried to do so. Other reports said that the seat would devour any person who had presumed themselves worthy enough to sit on it.
The seat was said to have cracked when Perceval sat in it, but it was later healed when he became a Grail Knight.
When Lancelot sinned by cavorting with Lady Guinevere his chance to sit in the chair and his chance to see the holy grail were forfeited. His son Galahad was the one to occupy the chair.
Sir Galahad eventually sat at the Siege Perilous. Although Percival was the first Knight to “see” the Holy Grail, Galahad completed the Quest. Ironically, Galahad is the son of Elaine and Lancelot.
Sonoma A well renowned wine producing region in California. It is adjacent to, and just north/north east of the Napa Valley region.
Wakoku Ancient name for Japan
Yamato – Area of Japan long ago (the Kanto area of ancient Japan)

– A city close to Osaka on the south/central end of Japan. Also the 3 Yamato Mountains is the name as a whole of Unebi-yama, Miminashi-yama, Amano-kaguyama mountains located in the north of Asuka region. They are separated 3 km from each other and form a triangle: capital Fujiwara-kyo is in the central low land.

TV Animation series starring a group of highly skilled and carefully selected young people under the command of Captain Avatar.
