How to bind my domain to my IP via ns*.he.net

[JustCraft]

People, please could someone explain me how to bind my already registered properly delegated to ns*.he.net domain with my IP which is not static ???

1. I have registered and paid domain: mc-rpg.ru
2. all 4 available links for DNS delegation properly installed for ns*.he.net servers

P.S. I've already tried to create tunnel but I can't ping my PC via mc-rpg.ru
