They don't know why and they think that the problem is maybe from cpanel... * I just reinstall the cpanel and was auto detect my vps ethernet as venet0:0 (i was check using ifconfig and checking in the ip) and it was ok and at the nameservers ns1.mydomain.com and ns2.mydomain.com it auto adds 2 ip's (that exists in my ip pool in hypervm) but i don't want to use them in that vps and even if i change them they look ok in dnz zone in whm but if i go to basic configuration and press Add a A entry for this nameserver i can see there the old one and when i delete them from the dns zone and add the ip that i want to use it says all ok but then i got again the same ip Maybe i did something wrong at first steps of setup in whm that it was asking: Thanks
