Analysis

Hierarchy

classical.org serves as the parent of bernstein.classical.org and www.classical.org.

IP Addresses

classical.org has two IP addresses: 3.210.83.108 and 100.57.247.197

www.tvscience.org, tvscience.org, ec2-3-210-83-108.compute-1.amazonaws.com plus two other host names have IP numbers in common with classical.org.

Name Servers

Four name servers handle the delegation for classical.org: ns-33.awsdns-04.com, ns-666.awsdns-19.net, ns-1517.awsdns-61.org and ns-1629.awsdns-11.co.uk.

There is at least partial name server overlap between classical.org and other domains — savewsfl.com, cmssi-doors.com, aizebizplus.jp and two more among them.

All four hostnames — ns-33.awsdns-04.com, ns-666.awsdns-19.net, ns-1517.awsdns-61.org and ns-1629.awsdns-11.co.uk — resolve to two IP numbers apiece: ns-33.awsdns-04.com to 205.251.192.33 and 2600:9000:5300:2100::1; ns-666.awsdns-19.net to 205.251.194.154 and 2600:9000:5302:9a00::1; ns-1517.awsdns-61.org to 205.251.197.237 and 2600:9000:5305:ed00::1; ns-1629.awsdns-11.co.uk to 205.251.198.93 and 2600:9000:5306:5d00::1.

Mail Servers

classical.org uses one mail server — classical-org.mail.protection.outlook.com.

classical-org.mail.protection.outlook.com has 8 IP addresses: 52.101.10.12, 52.101.11.9, 52.101.41.22 plus 5 more.
