Analysis

Name Servers

Two name servers dns1.registrar-servers.com and dns2.registrar-servers.com handle delegation for slack.us.com.

slack.us.com uses the same name server setup as other domains, for example superfunawesometime.com, lightworksinternational.com, elizabethschooloflondon.uk, channelsky.com and blackopsonly.com.

slack.us.com shares name servers with other domains at least partially, for instance tek-mix.com, sonlightsc.com, jenkinsbrown.com and rippleeft.com.

These name servers are commonly used with dns3.registrar-servers.com, dns4.registrar-servers.com and dns5.registrar-servers.com.

Host names with two IP numbers:

dns1.registrar-servers.com points to: 2610:a1:1024::200 and 156.154.132.200

dns2.registrar-servers.com points to: 2610:a1:1025::200 and 156.154.133.200

Mail Servers

Five mail servers handle slack.us.com: eforward1.registrar-servers.com, eforward2.registrar-servers.com, eforward3.registrar-servers.com, eforward4.registrar-servers.com and eforward5.registrar-servers.com.

slack.us.com shares some mail servers with other domains, at least partially, such as capitalpreferrevivestreambase.xyz, tele-starapp.sbs, write4kids.com, iamnop.com and marketecture.com.

Hostnames with a single IP:

eforward1.registrar-servers.com points to: 162.255.118.51

eforward2.registrar-servers.com points to: 162.255.118.52

eforward3.registrar-servers.com points to: 162.255.118.51

eforward4.registrar-servers.com points to: 162.255.118.52

eforward5.registrar-servers.com points to: 162.255.118.51

Hostnames pointing to 162.255.118.51: eforward1.registrar-servers.com, eforward3.registrar-servers.com and eforward5.registrar-servers.com

Hostnames pointing to 162.255.118.52: eforward2.registrar-servers.com and eforward4.registrar-servers.com

Common pattern: three hostnames point to 162.255.118.51 and two point to 162.255.118.52.
