Analysis
Name Servers
The domain optimizationblog.com is delegated to these four name servers: ns-cloud-c1.googledomains.com, ns-cloud-c2.googledomains.com, ns-cloud-c3.googledomains.com and ns-cloud-c4.googledomains.com.
There is at least partial name server overlap between optimizationblog.com and other domains — xsvoid.com, sumit.media, unitedbuildingsupply.net and two more among them.
These name servers tend to appear in combination with the name servers ns-127.awsdns-15.com, ns-664.awsdns-19.net, ns-1424.awsdns-50.org and ns-1660.awsdns-15.co.uk.
All four hostnames — ns-cloud-c1.googledomains.com, ns-cloud-c2.googledomains.com, ns-cloud-c3.googledomains.com and ns-cloud-c4.googledomains.com — resolve to two IP numbers apiece: ns-cloud-c1.googledomains.com to 216.239.32.108 and 2001:4860:4802:32::6c; ns-cloud-c2.googledomains.com to 216.239.34.108 and 2001:4860:4802:34::6c; ns-cloud-c3.googledomains.com to 216.239.36.108 and 2001:4860:4802:36::6c; ns-cloud-c4.googledomains.com to 216.239.38.108 and 2001:4860:4802:38::6c.
