Dear Friends
I have an issue for resolving DNS from internal domain to external on the company, I'll try to explain it...
I have an internal domian as domain.com with AD DS services DNS and DHCP only for internal users.
The company has a web page hosped on third party provider with the same domain as domain.com.
Internelly users cannot resolve the web page because is out company, but I tried to create a record with its Public IP and hostname and I think it works.
On DNS Server has DNS forwarders and root hints and it works ok.
My question is, is it valid to create a record with an Public IP on the internal DNS?
Could anyone help me ? Which is the better recommendation or What Should I configure?
Best regards
Luis Reyes
