Americas region realm list by datacenter

Realms in the Americas region are hosted for Blizzard in several datacenters across the United States and Australia. They are located in:
 * Chicago, Illinois (moved from Dallas, Texas in June 2010)
 * Los Angeles, California
 * Sydney, Australia (moved from Los Angeles on October 28, 2014)

While new players often wish to choose a realm matching their own time zone, those realms may actually be located far away from them. For example, some servers in Los Angeles have realms on US Eastern Time, and some servers in Chicago have realms on US Pacific Time. Instead, players may first wish to pick a datacenter to which they have good internet connectivity.

To that end, this is a list of US realms organized by datacenter, battlegroup, time zone, and realm type. Also included are the IP addresses of each realm server, and the IP address of the last hop from the player's computer to the server when doing a traceroute.


 * If your server's IP address is wrong, please feel free to update it.

Blizzard also has posted a list of IP addresses, which may not be up-to-date during the process of hooking up Connected Realms.

Time zones
The following tables have abbreviated time zones in an effort to conserve space. Those abbreviations and the full time zones are:

Chicago
When doing a traceroute to servers in Chicago, please trace to the following IP address: 63.240.161.189

Update: 09/22/2020

This seems to be labeled as "US Central" now under IP address: 24.105.62.129

Los Angeles
When doing a traceroute to servers in Los Angeles, please trace to the following IP address: 12.129.209.68

Update: 09/22/2020

This seems to be labeled as "US West" now under IP address: 137.221.105.2

Australia
Realms physically located in Australia were opened on October 28, 2014. For matchups only involving players on Oceanic realms, instances (like battlegrounds or raids) will also be physically located in Australia. However, should matchups involve players on non-Oceanic realms, instances will be physically located on whichever server is closest to the leader.

When doing a traceroute to Oceanic realms, please trace to the following address: 103.4.115.248

Update: 09/22/2020

This seems to be labeled as "Oceania" now under same IP address as above.
