Four name servers handle the delegation for gd-u.com: ns-cloud-c1.googledomains.com, ns-cloud-c2.googledomains.com, ns-cloud-c3.googledomains.com and ns-cloud-c4.googledomains.com.

At least some of gd-u.com's name servers are shared with other domains, for example mavency.com, counterpointpos.com, davidhernandezchicago.com and two more.

Four hostnames, each resolving to a pair of IP addresses: ns-cloud-c1.googledomains.com directs to 216.239.32.108 and 2001:4860:4802:32::6c; ns-cloud-c2.googledomains.com directs to 216.239.34.108 and 2001:4860:4802:34::6c; ns-cloud-c3.googledomains.com directs to 216.239.36.108 and 2001:4860:4802:36::6c; ns-cloud-c4.googledomains.com directs to 216.239.38.108 and 2001:4860:4802:38::6c.

Mail Servers

gd-u.com uses two mail servers, smtp.google.com and aspmx.l.google.com.

The mail server setup of gd-u.com matches that of other domains such as polloni.net, saarmail.eu, global-teleradiology.com and two others.

At least some of the mail servers used by gd-u.com are shared with other domains: bayar.realtor, tasteboudoir.com, ns500742.ns500754.ns500754.ns500742.ns500742.ns500731.ns500704.ns500671.ns500671.ns500671.ns500671.ns500666.ns500131.lustychickser.com and two others among them.

These mail servers are often deployed together with alt1.aspmx.l.google.com, alt2.aspmx.l.google.com, alt3.aspmx.l.google.com and 4 other mail servers.

Hosts with 9 IP addresses each:

smtp.google.com has IP addresses 142.250.31.27, 172.253.115.26 and 172.253.115.27, plus 6 other.

Host names pointing to two IP addresses:
