 Hi

Firstly, thank you all for the good posts on Secondary DNS which has given
 this newbie much food for thought. The most interesting post for me was the
one below by Norbert. But before a word about that, perhaps I was not
elementary enough in stating the problem. The server was set up with a host
 name, domain name, a Primary DNS and a Secondary DNS and a default gateway
 address. I moved my site from a previous IP and mistakenly perhaps replaced
 its previous Primary Name Server address and its Secondary Name Server
 address  with internic with the default site settings of Primary Name
Server
 address and its Secondary Name Server address for the RAQ3 which I had been
 given with the server, I did this  in order to point internic to my website
 at its new location with all its files etc uploaded to the RAQ3 replacing
 previous default raq hostname and its default host template. The problem
was
 that the default template was being accessed through the default gateway
 address and not the Primary DNS above. No problem. so I changed on internic
 the Primary IP to point to the default gateway. This is where the Secondary
 DNS problem kicked in ie what address to choose for it. Taking a chance I
 gave it the original default secondary dns address given to me on setting
up
 the server, but feel the sands shifting under my confidence and at this
 point I intend to perhaps use a public dns server for this purpose and
 register this change in due course with copernic.

 Norbert`s settings below are interesting in that the settings at this level
 are not accessible through the control panel on RAQ3 but are even more
 interesting from the point of view as to 'where'/'how' and more
particularly
 'why' name server settings at this level need to be implemented, so if
 anyone has any urls to educate me on these points I would be very grateful.

 Thank you Norbert for your information. As a newbie the above is about as
 far as I will take this on the list, so if anyone got any final
suggestions,
 they will be gratefully received. As I said before, this issue of moving a
 website to the server via internic could be better done in the docs,
 particularly the issue of secondary name server.

 Best regards

 Colm
