Name servers?

[Guest]

I am going to sign up for your $25/yr special on Sunday but I don't want to wait for domain propogation :)

What are the two name servers I should use?

[Joe]

currently -

ns10a.hostpc.com
ns10b.hostpc.com

[Slumpack]

My domain currently registered at godaddy and i just sign up for new webhosting and i receive this nameserver :
ns3a.hostpc.com --> 63.247.79.146
ns3b.hostpc.com --> 63.247.79.147

but when i try to ping the ip address i get timeout request

I would like use godaddy nameserver and point it to my webhost IP address but i could not ping the IP ?? maybe ping function is disabled ??

thanks
