www.a.co is a child of a.co.

Three IP numbers, 54.239.16.179, 54.239.20.248, and 54.239.21.27, are pointed to by a.co.

For instance, other host names like amz.onl share IP numbers with a.co.

The delegation of a.co is done to six name servers, namely pdns5.ultradns.info, pdns1.ultradns.net, pdns2.ultradns.net, pdns3.ultradns.org, pdns4.ultradns.org, and pdns6.ultradns.co.uk.

Name servers of a.co are at least partially shared with other domains such as weeatimpossible.com, sdge.net, ffluor.com, food4u.com, and jhnet.com.

The name servers udns1.ultradns.net, udns2.ultradns.net, dns1.p01.nsone.net, dns2.p01.nsone.net, dns3.p01.nsone.net, dns4.p01.nsone.net, dns1.p09.nsone.net, dns2.p09.nsone.net, dns3.p09.nsone.net, and dns4.p09.nsone.net are frequently used in tandem.

pdns5.ultradns.info, pdns1.ultradns.net, pdns2.ultradns.net, pdns3.ultradns.org, pdns4.ultradns.org, and pdns6.ultradns.co.uk all point to two IP numbers each: 2610:a1:1016::1, 204.74.114.1, 2001:502:f3ff::1, 204.74.108.1, 2610:a1:1014::1, 204.74.109.1, 2610:a1:1015::1, 199.7.68.1, 2001:502:4612::1, 199.7.69.1, 2610:a1:1017::1, and 204.74.115.1 respectively.
