react.school maps to 4 IP numbers, specifically 18.208.88.157, 98.84.224.111, 2600:1f18:16e:df01::258 and 2600:1f18:16e:df01::259.

Two other host names, along with www.burakdev.com, tourhane.netlify.com and testdrive05.netlify.com, also share IP numbers with react.school.

react.school delegates DNS authority to 4 name servers β€” dns1.p02.nsone.net, dns2.p02.nsone.net, dns3.p02.nsone.net and dns4.p02.nsone.net.

There is at least partial name server overlap between react.school and other domains β€” barksdaledesign.com, hawkhandsaw.com, activetrail.net and two more among them.

These name servers co-occur with ns01.squarespacedns.com, ns02.squarespacedns.com, ns03.squarespacedns.com and seven other name servers on a regular basis.

All four hostnames β€” dns1.p02.nsone.net, dns2.p02.nsone.net, dns3.p02.nsone.net and dns4.p02.nsone.net β€” resolve to two IP numbers apiece: dns1.p02.nsone.net to 198.51.44.2 and 2620:4d:4000:6259:7:2:0:1; dns2.p02.nsone.net to 198.51.45.2 and 2a00:edc0:6259:7:2::2; dns3.p02.nsone.net to 198.51.44.66 and 2620:4d:4000:6259:7:2:0:3; dns4.p02.nsone.net to 198.51.45.66 and 2a00:edc0:6259:7:2::4.
