Analysis

Name Servers

The domain ustcg.com is delegated to these four name servers: ns1.whois.com, ns2.whois.com, ns3.whois.com and ns4.whois.com.

ustcg.com partially shares its NS delegation with several other domains, including 2theuniverse.com, babbilon.com, mgk.mobi and two others.

These name servers often co-occur with the name servers 208.91.197.91.

Each of the host names ns1.whois.com, ns2.whois.com, ns3.whois.com and ns4.whois.com resolves to four IP addresses: ns1.whois.com resolves to 162.251.82.122, 162.251.82.123, 162.251.82.250 and 162.251.82.251; ns2.whois.com resolves to 162.251.82.120, 162.251.82.121, 162.251.82.248 and 162.251.82.249; ns3.whois.com resolves to 162.251.82.118, 162.251.82.119, 162.251.82.246 and 162.251.82.247; ns4.whois.com resolves to 162.251.82.124, 162.251.82.125, 162.251.82.252 and 162.251.82.253.

Mail Servers

ustcg.com uses three mail servers — us2.mx1.mailhostbox.com, us2.mx2.mailhostbox.com and us2.mx3.mailhostbox.com.

ustcg.com shares at least some of its mail servers with other domains — for example yaa.com.hk, analytical-decisions.com, wenepali.com and two more.

These mail servers tend to be used in conjunction with aspmx.l.google.com, alt1.aspmx.l.google.com, alt2.aspmx.l.google.com and two additional mail servers.

The hostnames us2.mx1.mailhostbox.com, us2.mx2.mailhostbox.com and us2.mx3.mailhostbox.com each resolve to a single IP: us2.mx1.mailhostbox.com → 162.215.3.26, us2.mx2.mailhostbox.com → 162.215.2.27, us2.mx3.mailhostbox.com → 162.215.3.25.
