We pick e.root-servers.net, one of the 13 root servers (1), and ask it about iab.org and learn that org is delegated to six name servers (2), so we ask b0.org.afilias-nst.org where we learn that iab.org is delegated to six name servers, including ns0.ietf.org (3), so we ask that one and get the following answer:

A4wp.org, velocitystrategicevents.com, affiliascorporation.info, url.info, affilliasmembers.info and at least 103 other hosts share name servers under another name with this domain. Apps.ietf.org, ns0.ietf.org, mail.ietf.org, iaoc.ietf.org, www.ietf.org and at least nine other hosts share mail servers with this domain. Iab.keio.ac.jp and iab.nsw.gov.au are similar domain names.

Also check www.iab.org.

Iab.org is hosted on two servers in Fremont, CA, United States.

The name server ns0.ietf.org
All of the nine domains that use the name server ns0.ietf.org use the six name servers ns0.ietf.org, ns1.ams1.afilias-nst.info, ns1.hkg1.afilias-nst.info, ns1.mia1.afilias-nst.info, ns1.sea1.afilias-nst.info and ns1.yyz1.afilias-nst.info together, hereafter referred to as "name server group 1", (example: rfc-ed.com, rfc-editor.com and rfc-ed.net ).

The mail server mail.ietf.org
All of the about twenty domains that use the mail server mail.ietf.org use only the mail server mail.ietf.org (example: datatracker.ietf.org, ftp.ietf.org and jabber.ietf.org ).

The name server ns1.hkg1.afilias-nst.info
Most of the several hundred of domains that use the name server ns1.hkg1.afilias-nst.info use the five name servers ns1.ams1.afilias-nst.info, ns1.hkg1.afilias-nst.info, ns1.mia1.afilias-nst.info, ns1.sea1.afilias-nst.info and ns1.yyz1.afilias-nst.info together, hereafter referred to as "name server group 2", (example: publicir.org, afilaismembers.info and afilliasmember.info ).

The six name servers ns0.ietf.org, ns1.ams1.afilias-nst.info, ns1.hkg1.afilias-nst.info, ns1.mia1.af…
Nine of the 13 domains that use name server group 1 point to the two IP numbers 2001:1890:126c::1:2f and 64.170.98.47 together (example: rfc-editor.org ).

The five name servers ns1.ams1.afilias-nst.info, ns1.hkg1.afilias-nst.info, ns1.mia1.afilias-nst.inf…
