Two other host names, along with www.thespruce.com.cdn.cloudflare.net, www.promocodesforyou.com.cdn.cloudflare.net and simplyrecipes.com, also share IP numbers with about.com.

Name Servers

Three name servers are authoritative for about.com: blue.foundationdns.com, blue.foundationdns.net and blue.foundationdns.org.

The name servers of about.com overlap at least partially with those of other domains — among them beeswaxfarming.co.uk, 4.98.155.in-addr.arpa, idxsupplierportal.com and two more.

These name servers commonly appear in delegations together with ns.utah.edu, dns1.p01.nsone.net, dns2.p01.nsone.net and 4 other.

DNS names with 6 IP addresses:

Mail Servers

Five mail servers handle about.com: aspmx2.googlemail.com, aspmx3.googlemail.com, aspmx.l.google.com and two others.

There is at least a partial MX overlap between about.com and other domains, including ns500693.ns500693.ns500693.ns500693.ns500693.ns500693.ns500693.ns500699.ns500693.ns500699.ns500588.ns500588.ns500588.ns500588.dtrkdll.com, ns500759.ns500698.ns500698.ns500759.ns500758.ns500736.ns500698.ns500735.ns500735.ns500708.ns500576.ns500686.ns500576.trackreceptor.com, ns500758.ns500758.ns500758.ns500759.ns500758.ns500698.ns500698.ns500735.ns500698.ns500708.ns500698.trackreceptor.com and two others.
