(ns12,dns12).ovh.net.
We pick f.root-servers.net, one of the 13 root servers (1), and ask it about highft.com and learn that com is delegated to 13 name servers (2), so we ask b.gtld-servers.net where we learn that highft.com is delegated to two name servers, including ns12.ovh.net (3), so we ask that one and get the following answer:
Highft.com is a domain controlled by two domain name servers at ovh.net having a total of four IP numbers. Some of them are on the same IP network. Incoming mail for highft.com is handled by three mail servers also at ovh.net having a total of eight IP numbers. All eight of them are on the same IP network. Highft.com has one IP number (213.186.33.2).
All of the several thousand of domains that use the primary name server dns12.ovh.net use name server group 1 (example: tempsdem.fr, legouvernement.fr and jlsnet.info ). Worth noting is that about one in six of the domains that use name server group 1 use the primary name server dns12.ovh.net.
The last resort mail server mxb.ovh.net only
There are several thousand of domains that use the last resort mail server mxb.ovh.net.
The three mail servers mx1, mx2 and mxb.ovh.net together

The three mail servers mx3, mx4 and mxb.ovh.net together
There are several thousand of domains that use the three mail servers mx3, mx4 and mxb.ovh.net together, hereafter referred to as "mail server group 3".
Half of those point only to the IP number 213.186.33.2.
Half of them use only the IPv4 number 213.186.33.2. Worth noting is that seven percent of the domains that only use the IPv4 number 213.186.33.2 use mail server group 3.
The two mail servers mx1 and mx2.ovh.net together
