Analysis

Hierarchy

a.io is a parent of ns3.a.io, ns2.a.io, ns4.a.io, www.a.io, dns2.a.io and a few other host names.

IP Addresses

a.io points to a single IP address: 85.10.133.119.

Other host names such as www.worldofdomains.com, domainearl.com, xrnames.com, foundationnames.com and upgrade.nyc share IPs with a.io.

Name Servers

a.io is delegated to four name servers: ns1.a.io, ns2.a.io, ns3.a.io and ns4.a.io.

a.io at least partially shares name servers with other domains, for example aserv.net, a.mk, earltindolbodyshop.com, a.gd and a.ms.

these name servers commonly pair with ns1.aserv.net, ns2.aserv.net, ns3.aserv.net and ns4.aserv.net.

Host names with two IP numbers:

ns1.a.io points to: 2a06:fb00:1::1:251 and 185.136.96.251

ns2.a.io points to: 2a06:fb00:1::2:251 and 185.136.97.251

ns3.a.io points to: 2a06:fb00:1::3:251 and 185.136.98.251

ns4.a.io points to: 2a06:fb00:1::4:251 and 185.136.99.251
