Hierarchy

The domain mail.linuxgnu.net falls under the parent linuxgnu.net.

IP Addresses

linuxgnu.net points to the four IP addresses 104.21.9.207, 172.67.131.7, 2606:4700:3032::ac43:8307 and 2606:4700:3033::6815:9cf.

q9txdf.mom, bahiscasinodiscount3.com, land-rover.dealerzy.com plus two other host names have IP numbers in common with linuxgnu.net.

Name Servers

Two name servers handle the delegation for linuxgnu.net: katelyn.ns.cloudflare.com and maciej.ns.cloudflare.com.

The name server configuration of linuxgnu.net is shared with other domains, for instance radelgroup.com, larsmiddel.com, crossislandcomputers.com and two others.

At least some of linuxgnu.net's name servers are shared with other domains, for example unreleased.co.uk, npdnj.org, sunriseen.com and two more.

These name servers tend to be deployed in combination with the name servers eve.ns.cloudflare.com and reese.ns.cloudflare.com.

Hosts with 6 IP addresses each:

katelyn.ns.cloudflare.com resolves to 108.162.194.235, 162.159.38.235 and 172.64.34.235 among others, with 3 other IP addresses in total.

maciej.ns.cloudflare.com resolves to 108.162.195.42, 162.159.44.42 and 172.64.35.42 among others, with 3 other IP addresses in total.

Mail Servers

linuxgnu.net uses one mail server — mail.linuxgnu.net.

linuxgnu.net uses the same mail servers as other domains, including sbmc.dev.

mail.linuxgnu.net directs to two IP numbers, 159.195.4.193 and 2a00:11c0:5f:4e33:8d5:99ff:fe37:1e00.
