Analysis

Name Servers

Two name servers dns1.registrar-servers.com and dns2.registrar-servers.com are delegated to smartbook.us.

smartbook.us uses the same name server configuration as other domains, such as siampants.com, ekeropartnersempowerwealth.com, securesub.com, bullmastiff.dog and on247.me.

smartbook.us at least partially shares name servers with other domains such as nerdsonsitetestimonials.com, ancientrealm.com, doglp.com, brgns.com and teamlatex.com.

These name servers are commonly used alongside dns3.registrar-servers.com, dns4.registrar-servers.com and dns5.registrar-servers.com.

Host names with two IPs:

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.
