Hey I got a server that I code and help out for here's the IP, use a standard 508 IP Changer.
Firescapepvp.no-ip.biz -- Check its current status here.
I like the server so much because I code for it, I'm admin in it (dumb reasons but here comes better ones) there's a lot of people online, and I mean A LOT, and it has a stable economy. (Some people got lucky before the economy update though and are rich)
It has a training arena, ancients work, staff are nice and enforce the rules, there are 2 coders (Me and Owner Star) there's tons of updates, and much more!
