You can point a DNS to pretty much anything you want. The DNS server itself
has no idea about public and private IP.
Chances are that the owner of the Domain uses it for internal stuff as well,
it's totally legit.

> I was browsing the web pages users on our network had requested, and saw a
website called inbound.registeredsite.com. This address resolves to
18.104.22.168, which is to my knowledge a valid IP address.
> However, when I see URLs that don't answer web requests, I usually chop
off the third level part of the DNS name and replace it with 'WWW', which
left me browsing to www.registeredsite.com. Oddly enough, this resolves to
10.0.0.1 which I am sure is a private IP. I didn't even know that DNS
servers would resolve DNS names to private IPs.
> Registeredsite.com is owned by Network Solutions. How would they benefit
from pointing people to a private IP address? Does it conform to the DNS
RFCs to associate a private IP to a public DNS server?
