Analysis

Hierarchy

opt4.com sits above nsfmt.opt4.com, nsberk.opt4.com and bounce.opt4.com in the domain hierarchy.

IP Addresses

opt4.com points to the IP addresses 15.156.29.54 and 15.175.34.40

b-e-d.com, www.forum.mitrella.com, comiva.com plus two other host names have IP numbers in common with opt4.com.

Name Servers

Four name servers handle the delegation for opt4.com: amsterdam.power-dns.com, ns1.power-dns.com, ns2.power-dns.com and ns3.power-dns.com.

There is at least partial name server overlap between opt4.com and other domains — ebay.premiumtips.com, towat.com, rouske.com and two more among them.

These name servers frequently co-occur with the name servers ip-172-26-1-146.us-east-2.compute.internal and singapore.power-dns.com.

ns1.power-dns.com points to 13.58.50.225; ns2.power-dns.com points to 188.166.142.159; ns3.power-dns.com points to 139.59.220.175 — each hostname maps to exactly one IP address.

Mail Servers

opt4.com uses two mail servers, mx1.ewebdevelopment.com and mx2.ewebdevelopment.com.

The mail server setup of opt4.com matches that of other domains such as homelo.com, gd-s.com, cdzt.com and two others.

mx1.ewebdevelopment.com → 159.203.54.48 and mx2.ewebdevelopment.com → 188.166.142.73: one IP number per host name.
