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 email@example.com twitter.com firstname.lastname@example.org ycombinator.com email@example.com, firstname.lastname@example.org wikipedia.com email@example.com spiegel.de firstname.lastname@example.org bmw.com *emphasized email@example.com, firstname.lastname@example.org heise.de email@example.com baidu.com firstname.lastname@example.org microsoft.com email@example.com, firstname.lastname@example.org amazon.com email@example.com linkedin.com firstname.lastname@example.org ebay.com email@example.com
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.
