Name Servers

u4e.net has four authoritative name servers: cp1.privatesystems.net, cp2.privatesystems.net, cp3.privatesystems.net and cp4.privatesystems.net.

There is at least partial name server overlap between u4e.net and other domains — masterdentalny.com, searchmarketingservice.com, amarbikrampur.com and two more among them.

The four hostnames cp1.privatesystems.net, cp2.privatesystems.net, cp3.privatesystems.net and cp4.privatesystems.net each resolve to two IP addresses. cp1.privatesystems.net points to 158.106.136.90 and 2600:4c00:80:11::1. cp2.privatesystems.net points to 108.160.157.7 and 2600:4c00:509:731::a. cp3.privatesystems.net points to 158.106.136.36 and 2600:4c00:80:9::1. cp4.privatesystems.net points to 158.106.136.90 and 2600:4c00:80:11::1 — the same pair as cp1.privatesystems.net.
