We pick f.root-servers.net, one of the 13 root servers (1), and ask it about pornobrigade.net and learn that net is delegated to 13 name servers (2), so we ask g.gtld-servers.net where we learn that pornobrigade.net is delegated to two name servers, including ns69.domaincontrol.com (3), so we ask that one and get the following answer:
Pornobrigade.net is a domain controlled by two domain name servers at domaincontrol.com having a total of four IP numbers. All four of them are on different IP networks. Incoming mail for pornobrigade.net is handled by two mail servers at secureserver.net having a total of three IP numbers. There are three duplicated IP numbers. Two of them are on the same IP network. Pornobrigade.net has two IP numbers (184.168.221.75, 66.96.147.108). Both are on different IP networks.
The two name servers ns71 and ns72.domaincontrol.com together
Most of the several thousand of domains that use name server group 3 use mail server group 1 (example: cookingclassisrael.com, roughneckservices.com and doortechelectronics.com ). Worth noting is that at least one of the domains that use mail server group 1 use name server group 3.
