Analysis
Name Servers
The domain firstclass.ru is delegated to these four name servers: a.ns.selectel.ru, b.ns.selectel.ru, c.ns.selectel.ru and d.ns.selectel.ru.
At least some of firstclass.ru's name servers are shared with other domains, for example u-on.travel, xn--80aueagpkl.xn--p1ai, betaproduction.ru and two more.
These name servers tend to be deployed in combination with the name servers ns1.baz-on.ru and ns2.baz-on.ru.
Four hostnames, each resolving to a pair of IP addresses: a.ns.selectel.ru directs to 188.68.203.1 and 2a00:ab00:800::2:53; b.ns.selectel.ru directs to 77.223.114.2 and 2a00:ab00:801::2:53; c.ns.selectel.ru directs to 188.68.203.3 and 2a00:ab00:802::2:53; d.ns.selectel.ru directs to 77.223.114.4 and 2a00:ab00:803::2:53.
