The delegation for sem.su is handled by three name servers: ns1.masterhost.ru, ns2.masterhost.ru and ns.masterhost.ru.

sem.su at least partially shares name servers with other domains, for instance dtg-printer.ru, exeed.ru, mensa.ru, belashop.ru and zobot.ru.

Two IP numbers per host:

ns1.masterhost.ru points to 2a00:15f8:a000:11:1:1:1:53 and 90.156.137.50.

ns2.masterhost.ru points to 2a00:15f8:a000:12:1:1:2:53 and 90.156.133.161.
