AI analysis

zdnet.com is the parent of enews.zdnet.com, gurgle.zdnet.com, cms.zdnet.com, japan.zdnet.com, www.zdnet.com and a few other host names.

zdnet.com resolves to two IP numbers: 199.232.194.154 and 199.232.198.154.

Other host names, for instance cnet.com, getinvisiblehand.com, priceblink.com and cnet.tech share IP numbers with zdnet.com.

zdnet.com is delegated to four name servers: ns-cloud-b1.googledomains.com, ns-cloud-b2.googledomains.com, ns-cloud-b3.googledomains.com and ns-cloud-b4.googledomains.com.

zdnet.com at least partially shares name servers with other domains, for instance wemba.net, zentotech.com, kurtcake.com, antlim.com and rapsodia.cl.

Host names with two IP numbers:

ns-cloud-b1.googledomains.com points to 2001:4860:4802:32::6b and 216.239.32.107; ns-cloud-b2.googledomains.com points to 2001:4860:4802:34::6b and 216.239.34.107; ns-cloud-b3.googledomains.com points to 2001:4860:4802:36::6b and 216.239.36.107; ns-cloud-b4.googledomains.com points to 2001:4860:4802:38::6b and 216.239.38.107.

zdnet.com is handled by a single mail server, smtp.google.com.

zdnet.com shares the same mail server setup as other domains, for instance argantec.com, paulagustin.com, asrockamerica.com, samariano.com and nubile.com.br.
