Analysis

IP Addresses

thecourse.org resolves to two IPs: 18.208.88.157 and 98.84.224.111.

other host names for instance modulust.fi, modest-kare-37e396.netlify.com, growbell.netlify.app, nifty-visvesvaraya-ecd621.netlify.com and career--viessmann-corp.netlify.com share IP numbers with thecourse.org.

Name Servers

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

thecourse.org at least partially shares name servers with other domains, for instance camurdanorman.com, saguru.jp, janssenconnectnetwork.com, boyrun.at and juliettephilogene.com.

These name servers are often used together with the name servers ns01.squarespacedns.com, ns02.squarespacedns.com, ns03.squarespacedns.com, ns04.squarespacedns.com, dns2.p01.nsone.net, dns3.p01.nsone.net, dns4.p01.nsone.net, connect1.squarespacedns.com, connect2.squarespacedns.com and ns01.jnjdns.com.

Hosts with two IP numbers:

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

dns1.p04.nsone.net points to 2620:4d:4000:6259:7:4:0:1 and 198.51.44.4.

dns2.p04.nsone.net points to 2a00:edc0:6259:7:4::2 and 198.51.45.4.
