I do not want to change the domain name. So, is it possible, and how to do this? Like - just to add names, which are NOT publicly visible, and are just for inhouse use.
If I've understood correctly, you'd like "mail.mydomain.com" to be resolved externally (by your ISPs name-server), but "sunny.mydomain.com" to be resolved internally by your own name-server?
You could always just run your own local server that would resolve all the names you want for "mydomain.com".
Of course, you'd have to keep your internal and external name-servers in sync, but that's not too complicated.

Yes, that's what I want. Just had a hope that I can cascade the resolution with master/slave servers, so I do not need to keep them in sync, i.e.: ISP DNS provides www, mail, etc. (publicly known names). Then, I would like to have one internal server at my COLO, which adds some internal names, like dmz1, dmz2, etc. And then I want to have in my office another DNS server, which is slave to the COLO one, and adds names for office computers. As I have VPN connection between the office and the COLO, I need the office machines to be able to resolve the COLO ones, but COLO machines do not have to know about office ones. As well as external users do not need to know about the internals at all. Anyway, looks like impossible, so I'll live with COLO DNS server knowing everything :) and trying to keep in sync with the ISP's DNS. And will make the office DNS server a slave of the COLO one. -- -- Svetoslav Milenov (Sunny) Windows is a 32-bit extension to a 16-bit graphical shell for an 8-bit operating system originally coded for a 4-bit microprocessor by a 2-bit company that can't stand 1 bit of competition.
