Name Servers

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

chicagoportauthority.com uses the same name server setup as other domains, including action777.club, broadstairsstpeters.co.uk, aduvata.com, promotecache.com and eaa174.org.

chicagoportauthority.com at least partially shares name servers with other domains; for instance amirmc.net, zixxledesign.com and qibeauty.in.

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.
