These name servers are often used with the name servers ns1.arandomserver.com and ns2.arandomserver.com.

Host names with one IP number: The host name ns1.hawkhost.com points to 198.252.96.100 and the host name ns2.hawkhost.com points to 198.252.97.100.

These mail servers are often used with the mail servers mx4.arandomserver.com.

The host name mx1.arandomserver.com points to 172.96.188.161, 198.252.99.3, 198.252.99.4 and 198.252.100.64.

The host name mx2.arandomserver.com points to 172.96.188.160, 198.252.99.3, 198.252.99.4 and 198.252.100.65.

The host name mx3.arandomserver.com points to 172.96.188.161, 198.252.99.1, 198.252.99.4 and 198.252.100.65.
