Analysis

Name Servers

clientheartbeat.com is delegated to two name servers: dns1.registrar-servers.com and dns2.registrar-servers.com.

clientheartbeat.com uses the same name server setup as other domains, including hd(0x706f726e)joy.com, barbaramiranda.com, mlslens.com, jparrish.co.uk and desupervised.com.

clientheartbeat.com partially shares name servers with other domains, for instance kiralanier.com, studyarabic.com, welte.photography and veganthaifood.com.

These name servers are often used together with dns3.registrar-servers.com, dns4.registrar-servers.com and dns5.registrar-servers.com.

Host names with two IP numbers:

dns1.registrar-servers.com points to 2610:a1:1024::200 and 156.154.132.200.

dns2.registrar-servers.com points to 2610:a1:1025::200 and 156.154.133.200.
