Subdomain pointing to GameServer IP

[JokerNut]

I was wondering if we have this ability to have subdomains point to gameserver ips, and if so how do I go about accomplishing this?


For example, I would use a subdomain codserver.xyz.com and when someone would type "/connect codserver.xyz.com" in their COD console they would connect to the cod server.


Thanks,

If your gameserver has a static IP address then contact support and ask them to set up an A record to point hte name you want to that IP. I don't think they would have a problem with this. If your IP is dynamic, however, I doubt they'll be able to help you because there is no way to automatically update the IP when it changes and the time to live on the DNS zones is too long to support a dynamic IP (in other words, every time your ISP changes your IP address you'd have to contact support to have them update the record and then wait two days for it to take effect).

I just had an idea. This probably isn't a "best practice" from a general effeciency standpoint, but if you do have a dynamic IP address and you want to use your JPC-hosted domain name to point to it, consider doing this:

1. Sign up for the Dynamic DNS service at DynDNS.org (its free). This will give you a domain name (such as you.dyndns.org) with a short TTL. Combined with the use on an update client, which you can download from their site (or one may be built in to your home router, if you use one) this service will keep track of your IP address and update its Zone files at regular, short intervals. I use this service and it works great.

2. Ask support to establish a CNAME record in your domain's zone file that points at the dyndns.org address you set up above.

What this will do: CNAMES map a domain name to another domain name. Normally in the DNS system names are mapped to IP addresses, but CNAMES allow you to alias one name to another. Normally this is done for names on the same second level domain, such as to map ftp.somedomain.com to the same IP as www.somedomain.com, but it can also map names to names on a different domain. What would happen in this example is, when a machine requests the IP of your game server from JPC's DNS servers, the DNS servers would reply "try this name instead" and would provide the DynDNS name that you've set up. The client machine would then have to look up the DynDNS name, which would resolve to an IP, and the user would be able to connect to your game.

Thanks for the info Jason. My gameservers are static IPs. I'll try and get it set up this weekend. My gaming group members will be soooo happy if it works.

Thanks, again!
