Analysis

Name Servers

Four name servers handle the delegation for rex.com.do: dns1.midominio.do, dns2.midominio.do, dns3.midominio.do and dns4.midominio.do.

rex.com.do has at least partial name server overlap with other domains, such as sertel.com.do, ccsi.org.do, superlama.com.do and two others.

Each of the host names dns1.midominio.do, dns2.midominio.do, dns3.midominio.do and dns4.midominio.do resolves to four IP addresses: dns1.midominio.do resolves to 162.251.82.122, 162.251.82.123, 162.251.82.250 and 162.251.82.251; dns2.midominio.do resolves to 162.251.82.120, 162.251.82.121, 162.251.82.248 and 162.251.82.249; dns3.midominio.do resolves to 162.251.82.118, 162.251.82.119, 162.251.82.246 and 162.251.82.247; dns4.midominio.do resolves to 162.251.82.124, 162.251.82.125, 162.251.82.252 and 162.251.82.253.

Mail Servers

rex.com.do is handled by five mail servers: aspmx.l.google.com, alt1.aspmx.l.google.com, alt2.aspmx.l.google.com and two others.

At least some of the mail servers used by rex.com.do are shared with other domains: pacprints.com, haveagood.holiday, beunity.com and two others among them.

These mail servers often appear in conjunction with the mail servers alt3.aspmx.l.google.com, alt4.aspmx.l.google.com, aspmx2.googlemail.com and aspmx3.googlemail.com.

Host names pointing to two IP addresses:

aspmx.l.google.com has two IP addresses: 142.251.111.27 and 2607:f8b0:4004:c1b::1b.

alt1.aspmx.l.google.com has two IP addresses: 108.177.123.27 and 2800:3f0:4003:c0f::1a.

alt2.aspmx.l.google.com has two IP addresses: 172.253.116.26 and 2a00:1450:400b:c02::1b.

alt3.aspmx.l.google.com has two IP addresses: 192.178.223.27 and 2a00:1450:4009:c0f::1b.

alt4.aspmx.l.google.com has two IP addresses: 172.253.157.27 and 2a00:1450:400c:c23::1b.
