I remember the claim that if you have registered
example.com you should never use
...@example.com for owner, admin-c, tech-c or zone-c. The reason given was that if the registrar goes bankrupt the domain
example.com also stops working. You could loose the domain if the NIC can't get in touch with you.
Now I can't find a source and doubt the validity of that claim. As long as nameserver and mail server stay up, the email address should be fine. I also checked what other companies do and I found that almost everyone uses its own primary domain.
google.com firstname.lastname@example.org twitter.com email@example.com ycombinator.com firstname.lastname@example.org, email@example.com wikipedia.com firstname.lastname@example.org spiegel.de email@example.com bmw.com *emphasized firstname.lastname@example.org, email@example.com heise.de firstname.lastname@example.org baidu.com email@example.com microsoft.com firstname.lastname@example.org, email@example.com amazon.com firstname.lastname@example.org linkedin.com email@example.com ebay.com firstname.lastname@example.org
Is there any foundation to the claim that you should never use your own domain name for WHOIS records?
P.S. Please don't argue that it's unlikely that registrars go bankrupt. I've been through that. It was a
de Domain and it fell back to DENIC. They sent a letter at the postal address of the WHOIS owner record (which was a German address and thankfully correct). I don't remember if they also sent an email.
