[Ascent]...DynDS host problem

[Akroma]

well i started my server yesterday but my friends cant connect if i use my DynsDS host name(spartanwow.game-server.cc) but when i change my internet service to use username and pass every time to connect..meaning a diferent IP every day, when i was in this congif they could connect with the IP(ex.201.205.234.1) and today i change my services to have a static IP but now my frienda cant connect with the Ip...so i was thinking if someone can help to put my DynsDS correctly so they can connect using that one
