AI analysis

The parent of data.rcn.net, nms.rcn.net, tac.rcn.net, mail.rcn.net, infoserv.rcn.net and a few other host names is rcn.net.

rcn.net resolves to a single IP: 207.172.16.156.

Other host names, for instance rcn4.rcn.com, javanet.com, www.javanet.com, www.erols.com and www.rcn.net share IP numbers with rcn.net.

rcn.net delegates to five name servers: auth1.dns.rcn.net, auth2.dns.rcn.net, auth3.dns.rcn.net, auth4.dns.rcn.net and master.dns.rcn.net.

rcn.net shares some name servers with other domains, for example amcelfresh.com, chgo.il.rcn.net, 207-172-240-214.c3-0.tlg-ubr1.atw-tlg.pa.cable.rcn.com, 192.164.216.in-addr.arpa and 225.71.206.in-addr.arpa.

These name servers are commonly used with the name servers master.dns.erols.net.

Host names with four IP numbers:

auth1.dns.rcn.net points to 2610:80:0:102::44, 2610:80:0:10e::20, 66.44.1.44 and 207.172.3.20

auth2.dns.rcn.net points to 2610:80:0:100::17, 2610:80:0:101::120, 207.172.11.14 and 207.237.14.120

auth3.dns.rcn.net points to 2610:80:0:10e::21, 2610:80:80::153, 207.96.3.153 and 207.172.3.21

auth4.dns.rcn.net points to 2610:80:0:103::9, 2610:80:0:10e::22, 207.172.3.22 and 208.59.89.9

Host names with one IP number:

master.dns.rcn.net points to 207.172.3.5

rcn.net is handled by a single mail server, rcn-net.mail.protection.outlook.com.

Host rcn-net.mail.protection.outlook.com points to eight IP numbers: 2a01:111:f403:c946::1, 2a01:111:f403:f804::1, 2a01:111:f403:f908::1, 2a01:111:f403:f90a::1, 52.101.10.1, 52.101.11.7, 52.101.40.2 and 52.101.41.28.
