Analysis

Hierarchy

class.com is a parent of georgiacyber.class.com, highpoint.class.com, upn.class.com, iforward.class.com, go2boss.class.com and a few other host names.

IP Addresses

class.com points to three IPs: 2620:12a:8000::2, 2620:12a:8001::2 and 23.185.0.2.

Other host names such as lakemarysurgerycenter.com, cielowind.com, cphss.org, phledresearch.org and mondavicenter.org share IPs with class.com.

Name Servers

class.com is delegated to four name servers: ns-68.awsdns-08.com, ns-722.awsdns-26.net, ns-1034.awsdns-01.org and ns-1777.awsdns-30.co.uk.

class.com at least partially shares name servers with other domains, for example centre-podiatrique.ca, contentauthor.dmscgi.com, mentor-info.com, vutmobile.com and prolendly.com.

These name servers are commonly used with ns-428.awsdns-53.com and ns-1043.awsdns-02.org and ns-1869.awsdns-41.co.uk.

Host names with two IP numbers:

ns-68.awsdns-08.com points to: 2600:9000:5300:4400::1 and 205.251.192.68

ns-722.awsdns-26.net points to: 2600:9000:5302:d200::1 and 205.251.194.210

ns-1034.awsdns-01.org points to: 2600:9000:5304:a00::1 and 205.251.196.10

ns-1777.awsdns-30.co.uk points to: 2600:9000:5306:f100::1 and 205.251.198.241

Mail Servers

class.com is handled by five mail servers: aspmx.l.google.com, alt1.aspmx.l.google.com, alt2.aspmx.l.google.com, alt3.aspmx.l.google.com and alt4.aspmx.l.google.com.
