We don't provide IP addresses for domain
delegation or cname pointing as we use load balancers to run your site.
Basically this means at any time your visitor may be directed to any one
of our webservers using a different IP address. If you point to just
one or a number of IP addresses, and your visitor is directed to a
different IP address, that customer may only see an error. It is
therefore not practical to provide IP addresses.
You can use the standard practice of providing name server addresses or
cname address which can be found in your administration panel under
Settings>Email and Domain Management>Domain Names, click Add new
domain or select the domain you have active and see the name servers
under "Changing nameservers" or the cname pointing too under "Changing
cname".
