subnets ??

[Webmaster - prayagonline.com]

hi,
        i am new to this domain business, however we have successfully completed
the test-environment.
no we need to fill
"- a subnet of no more than 64 hosts that your server will be
accessing our network from."

We have our server and the two nameservers ... so do we need to give that
here ?

THanks a lot,
Regards,
gaurav
