Analysis

Name Server Role

iohs.kr serves as a name server for itself — iohs.kr is its own authoritative name server.

ns1.cafe24.com, ns1.cafe24.co.kr and ns2.cafe24.com frequently serve as name servers alongside iohs.kr.

IP Addresses

iohs.kr points to the four IP addresses 183.111.139.232, 203.245.12.105, 203.245.12.118 and 203.245.12.125.

Additional host names — pthreex.com, coryo.co.kr, someblossom.co.kr and two others — share IP numbers with iohs.kr.

Name Servers

iohs.kr is delegated to five name servers: iohs.kr, ns1.cafe24.com, ns2.cafe24.com and two others.

There is at least partial name server overlap between iohs.kr and other domains — taxai.shop, camo-page.com, ntom.co.kr and two more among them.

These name servers regularly appear alongside ns2.cafe24.co.kr, dns1.cafe24.com, dns1.cafe24.co.kr and 4 other name servers in NS record sets.

Host names that resolve to five IP addresses:

ns1.cafe24.com points to 112.175.246.230, 112.175.246.231, 116.126.143.242 and two other IP addresses.

Host names resolving to four IP addresses:

iohs.kr resolves to four IP addresses — 183.111.139.232, 203.245.12.105, 203.245.12.118 and 203.245.12.125.

ns2.cafe24.com resolves to four IP addresses — 1.226.85.4, 1.234.0.4, 112.175.11.4 and 112.175.12.4.

ns1.cafe24.co.kr resolves to four IP addresses — 112.175.246.232, 112.175.246.233, 175.125.93.136 and 175.125.93.137.

ns2.cafe24.co.kr resolves to four IP addresses — 112.175.247.232, 112.175.247.233, 175.125.93.146 and 175.125.93.147.

The four mail servers for iohs.kr are alt1.aspmx.l.google.com, alt2.aspmx.l.google.com, alt3.aspmx.l.google.com and alt4.aspmx.l.google.com.

iohs.kr shares mail servers — at least in part — with other domains, including neoskin.se, tekkerwave.com, sharansaccounting.com.au and two others.

These mail servers are routinely found in combination with the mail servers aspmx.l.google.com, aspmx2.googlemail.com and aspmx3.googlemail.com.

All four hostnames — alt1.aspmx.l.google.com, alt2.aspmx.l.google.com, alt3.aspmx.l.google.com and alt4.aspmx.l.google.com — resolve to two IP numbers apiece: alt1.aspmx.l.google.com to 192.178.234.27 and 2800:3f0:4003:c14::1b; alt2.aspmx.l.google.com to 172.253.116.27 and 2a00:1450:400b:c02::1a; alt3.aspmx.l.google.com to 172.253.152.26 and 2a00:1450:4010:c22::1b; alt4.aspmx.l.google.com to 192.179.20.27 and 2404:6800:4000:1027::1b.
