Analysis

Hierarchy

knockoutjs.com serves as the parent of learn.knockoutjs.com and www.knockoutjs.com.

IP Addresses

knockoutjs.com directs to four IP numbers, which are 185.199.108.153, 185.199.109.153, 185.199.110.153 and 185.199.111.153.

aribrill.com, mehdishahdoost.github.io, tekdemo.github.io plus two other host names have IP numbers in common with knockoutjs.com.

Name Servers

Four name servers handle the delegation for knockoutjs.com: ns-114.awsdns-14.com, ns-728.awsdns-27.net, ns-1082.awsdns-07.org and ns-1879.awsdns-42.co.uk.

There is at least partial name server overlap between knockoutjs.com and other domains — nombolo.com, 206collab.com, avegas.games and two more among them.

All four hostnames — ns-114.awsdns-14.com, ns-728.awsdns-27.net, ns-1082.awsdns-07.org and ns-1879.awsdns-42.co.uk — resolve to two IP numbers apiece: ns-114.awsdns-14.com to 205.251.192.114 and 2600:9000:5300:7200::1; ns-728.awsdns-27.net to 205.251.194.216 and 2600:9000:5302:d800::1; ns-1082.awsdns-07.org to 205.251.196.58 and 2600:9000:5304:3a00::1; ns-1879.awsdns-42.co.uk to 205.251.199.87 and 2600:9000:5307:5700::1.

Mail Servers

knockoutjs.com uses two mail servers, mx1.improvmx.com and mx2.improvmx.com.

The mail server setup of knockoutjs.com matches that of other domains such as shenghaiautoparts.net, asburyparkreporter.com, ecru.co.uk and two others.

knockoutjs.com and a number of other domains — mdasc.org, massaleh.com, andreas-lemberger.de and diamondsofatlanta.com among them — share at least some of the same mail servers.

Hosts with 6 IP addresses each:

mx1.improvmx.com carries IP addresses 13.37.195.136, 15.236.236.160 and 35.181.18.45, with 3 other addresses beyond those.

mx2.improvmx.com carries IP addresses 13.36.107.63, 13.36.222.39 and 15.236.61.92, with 3 other addresses beyond those.
