Analysis

IP Addresses

rtclk.com directs to one IP number, which is 50.19.77.149.

Further host names like shiecron.com and ec2-50-19-77-149.compute-1.amazonaws.com overlap in IP numbers with rtclk.com.

Name Servers

The domain rtclk.com is delegated to these four name servers: ns-448.awsdns-56.com, ns-826.awsdns-39.net, ns-1103.awsdns-09.org and ns-1741.awsdns-25.co.uk.

There is at least partial name server overlap between rtclk.com and other domains — d1bd9axktm1611.cloudfront.net, gutwenger.at, circstream.com and two more among them.

All four hostnames — ns-448.awsdns-56.com, ns-826.awsdns-39.net, ns-1103.awsdns-09.org and ns-1741.awsdns-25.co.uk — resolve to two IP numbers apiece: ns-448.awsdns-56.com to 205.251.193.192 and 2600:9000:5301:c000::1; ns-826.awsdns-39.net to 205.251.195.58 and 2600:9000:5303:3a00::1; ns-1103.awsdns-09.org to 205.251.196.79 and 2600:9000:5304:4f00::1; ns-1741.awsdns-25.co.uk to 205.251.198.205 and 2600:9000:5306:cd00::1.

Mail Servers

rtclk.com routes its mail through a single mail server, inbound-smtp.us-east-1.amazonaws.com.

rtclk.com has the same mail server arrangement as a number of other domains, for example medcera.com, hypatia-org.slack.com, mega-cat.slack.com and two more.

rtclk.com shares at least some of its mail servers with other domains — for example gota.store, konverso.atlassian.net, vivocoin.atlassian.net and two more.

It is common to find these mail servers paired with the mail servers inbound-smtp.us-west-2.amazonaws.com.

inbound-smtp.us-east-1.amazonaws.com directs to five IP numbers: 3.211.210.226, 44.206.9.87, 44.210.166.32 and two others.
