203.in-addr.arpa delegates to five name servers: ns1.apnic.net, ns2.apnic.net, rirns.arin.net, ns3.lacnic.net and apnic.authdns.ripe.net.

203.in-addr.arpa at least partially shares name servers with other domains such as 0.119.203.in-addr.arpa, apia.org, 189.in-addr.arpa, 91.in-addr.arpa and 88.in-addr.arpa.

These name servers are often used together with ns4.apnic.net, ns3.afrinic.net, pri.authdns.ripe.net, manus.authdns.ripe.net, ns1.arin.net, ns2.arin.net, ns3.arin.net, arin.authdns.ripe.net, ns1.afrinic.net and ns2.afrinic.net.

Two IPs per host name:

ns1.apnic.net points to: 2001:dd8:e::53 and 203.119.42.53

ns2.apnic.net points to: 2001:ddd::53 and 203.119.95.53

rirns.arin.net points to: 2620:38:2000::53 and 199.253.249.53

ns3.lacnic.net points to: 2001:13c7:7002:3000::14 and 200.3.13.14

apnic.authdns.ripe.net points to: 2a13:27c0:30::9 and 193.0.9.9

Pattern: left IDs ascend by 9 (12, 21, 30, 39, 48); each pair of targets ascend by 9 (15/18, 24/27, 33/36, 42/45, 51/54)
