TheSandbox Servers have Dynamic IP addresses so if your looking for the [SA] server but can't find it using gamespy or another program like it, then try this:

1. Open TFC, NS or SC
2. Click "Find Servers"
3. Click "Favorites tab"
4. Click "Change filters"
5. In the Game box, select TFC, NS or SC
6. Click "add server"
7. Type: killerz.dns2go.com:27015 for TFC
   Type: killerz.dns2go.com:27016 for NS Aliens
   Type: killerz.dns2go.com:27017 for NS Marines
   Type: killerz.dns2go.com:27018 for SC
   If steam is installed, you can simply click the server address to connect to your server of choice.
8. Click "ok"

TheSandbox server of choice should now be listed in your favorites list. After that, any time that the [SA] servers IP# changes (does not refresh for some time) then just remove the server IP's from your favorites list and repeat the steps noted above.
