Analysis

Mail Server Role

appengine.us acts as its own mail server.

IP Addresses

appengine.us has two IP addresses: 170.249.236.168 and 2600:4c00:300:cf::fe

Additional host names — benevolentoutcome.com, protreeexperts.net, thegentlewaybook.com and two others — share IP numbers with appengine.us.

Name Servers

appengine.us has four authoritative name servers: cp1.privatesystems.net, cp2.privatesystems.net, cp3.privatesystems.net and cp4.privatesystems.net.

There is at least partial name server overlap between appengine.us and other domains — dsltd.ca, unten.org, marriagehelp.com and two more among them.

These name servers are routinely deployed together with the name servers ns1.icsmx.org.

The four hostnames cp1.privatesystems.net, cp2.privatesystems.net, cp3.privatesystems.net and cp4.privatesystems.net each resolve to two IP addresses. cp1.privatesystems.net points to 158.106.136.90 and 2600:4c00:80:11::1. cp2.privatesystems.net points to 108.160.157.7 and 2600:4c00:509:731::a. cp3.privatesystems.net points to 158.106.136.36 and 2600:4c00:80:9::1. cp4.privatesystems.net points to 158.106.136.90 and 2600:4c00:80:11::1 — the same pair as cp1.privatesystems.net.

Host names pointing to 2600:4c00:80:11::1 IP addresses: cp1.privatesystems.net and cp4.privatesystems.net.

Host names pointing to 158.106.136.90 IP addresses: cp1.privatesystems.net and cp4.privatesystems.net.

Mail Servers

appengine.us has a single mail server: appengine.us itself.

appengine.us carries two IP numbers: 170.249.236.168 and 2600:4c00:300:cf::fe.
