I've asked a tech in another company to point a domain they control (say, odddomain.com) at one of my IP addresses (188.8.131.52). Before this, it was pointed to their ip, nn.nn.nn.nn. He's emailed to say all is well and done.
and get told that ns27.domaincontrol.com is one of the two authoritative DNS for this domain.
So I run
dig odddomain.com @NS28.DOMAINCONTROL.COM
;; ANSWER SECTION: odddomain.com. 3600 IN A nn.nn.nn.nn odddomain.com. 3600 IN A 184.108.40.206 ;; AUTHORITY SECTION: odddomain.com. 3600 IN NS ns28.domaincontrol.com. odddomain.com. 3600 IN NS ns27.domaincontrol.com.
Same results for "dig odddomain.com @NS28.DOMAINCONTROL.COM"
Are the two inconsistent answers for odddomain.com's ip coming from different dns controllers? I'm not sure how I'd create a situation like this, so I don't know how to tell my colleague to fix it.
