Analysis

Hierarchy

first.org is the parent of conference.first.org, misp.first.org, imap.first.org, www.first.org, api.first.org and a few other host names.

IP Addresses

Eight IP numbers are targeted by first.org: 2a04:4e42::347, 2a04:4e42:200::347, 2a04:4e42:400::347, 2a04:4e42:600::347, 151.101.1.91, 151.101.65.91, 151.101.129.91 and 151.101.193.91.

other host names including baldwinfunmachine.bandcamp.com, fspotrecords.bandcamp.com, bear-garden.bandcamp.com, www.fighterx.bandcamp.com and jonlindsay.bandcamp.com share IP numbers with first.org.

Name Servers

first.org is delegated to eight name servers: dns1.p01.nsone.net, dns2.p01.nsone.net, dns3.p01.nsone.net, dns4.p01.nsone.net, dns1.p04.nsone.net, dns2.p04.nsone.net, dns3.p04.nsone.net and dns4.p04.nsone.net.

first.org at least partially shares name servers with other domains, for instance victims.ri.gov, integratedturfcare.com, rekthub.com, cstoboston.org and jnjmedtech.cn.

These name servers are commonly used with the following name servers: ns01.squarespacedns.com, ns02.squarespacedns.com, ns03.squarespacedns.com, ns04.squarespacedns.com, ns01.jnjdns.com, ns02.jnjdns.com, ns03.jnjdns.com, ns04.jnjdns.com, connect1.squarespacedns.com and connect2.squarespacedns.com.

Host names with two IPs:

dns1.p01.nsone.net has IPs 2620:4d:4000:6259:7:1:0:1 and 198.51.44.1.

dns2.p01.nsone.net has IPs 2a00:edc0:6259:7:1::2 and 198.51.45.1.
