Name Servers
21.cf uses two name servers for its delegation: dns1.cscdns.net and dns2.cscdns.net.
21.cf uses the same name servers as several other domains — among them chipotlesick.com, pricelessmulan.com, dacia-assurance.fr and two more.
At least some of 21.cf's name servers are shared with other domains, for example countrywide-rm.info and bankcardloanservice.net.
These name servers tend to be deployed in combination with the name servers ns101.bac.com and ns102.bac.com.
The two host names dns1.cscdns.net and dns2.cscdns.net each have a pair of IP addresses: dns1.cscdns.net has 156.154.130.100 and 2610:a1:1022::100, and dns2.cscdns.net has 156.154.131.100 and 2610:a1:1023::100.
