DNS

Just a small question. I have chrisharries.com registerd with godaddy. I
have my DNS server (server 2003) running here at home. Now at godaddy I have
an A record of chrisharries.com pointing to my home IP address and my server
has DNS ports forwaded on the router. If I set-up vpn.chrisharries.com on my
DNS server at home for my VPN connections, will external users be able to
access it. I ask this because I only have chrisharries.com registerd at
godaddy but is it fine that vpn would just be reslolved on my DNS server?

Hope that makes sense

Thanks
Chris

Most people should just leave their PUBLIC DNS with
GoDaddy (or their own Registrar) and run ONLY their
internal DNS themselves.
If I set-up vpn.chrisharries.com on my
DNS server at home for my VPN connections, will external users be able to
access it.

Well, if their is a record for VPN.chrisharies.com in your
DNS server then it will resolve that name. IF external
users can reach that DNS server on the correct ports they
can also resolve it.

Of course, the parent zone must delegate to the DNS server
with these records.

(Although I recommend NOT transferring your public DNS
to your own server, you have changed your DNS servers in
the Godaddy setup to your own, right?)

The world (of Internet users) will go to ".", find .com, and
from their find the delegation to your ZONE and specifically
to the DNS Servers authoritative for it.

Initially, when you set up at GoDaddy their servers would be
these authoritative servers UNTIL you change this. In the
default case you would add the record AT GoDaddy.

If you change the DNS server at Godaddy then you can
maintain it own your own servers (but this is a poor plan.)

Hi Herb thanks for getting back to me.

Basically, I dont want to transfer my public DNS to my server, that server
will deal with all internal quries. I am just wondering however, that
www.chrisharries.com or a ping to chrisharries.com will goto my home IP
address becuase I have an A record of chrisharries.com 82.x.x.x (home ip) at
godaddy. Everything else is kept the same, its still there Name Servers and
such like just that 1 A record. I am just wondering if I set-up
vpn.chrisharries.com on my internal DNS, will external people be able to
access that even with ONLY chrisharries.com at godaddy, so even though
VPN.chrisharries.com isnt registerd at godaddy, chrisharries.com is so it
will still resolve to my server?

Hope that makes sense
Chris

If you want to override a SINGLE (or a few) record(s) then just
create ZONES with the same CHILD name: myweb.chrisharried.com
would become an ENTIRE INTERNAL zone with a "blank" A-record
for the address.

This way it will only resolve that single name and not override anything
in the Public zone (one level higher) except perhaps that specific name
(if it also exists there.)

ALternatively you can run "Shadow DNS" and manually maintain every
public record internally also, along with any additions you wish.

I think we may be comming from different angles. What I am asking is, if i
create a zone on my home DNS server of vpn.chrisharries.com, even though I
only have an A record pointing to my home server at godaddy, will
vpn.chrisharries still be pointed at my home server.

You question is almost indecipherable so I will just
give the possibilities so you will get your answer or
can ask another question:

VPN.chrisharries will have precisely the IP address
(rather than 'point') that you give it in that Zone, at least
for any machine that queries the "home DNS" directly.

For those on the Internet, they will see what is in the
parent (chrisharries.com) and will only find your "home
DNS" IF there is a delegation for that name in the public
server at Godaddy. This would require an NS record
AND an A record for the "vpn" DNS server.
even though I only have an A record pointing to my home server at godaddy,
will vpn.chrisharries still be pointed at my home server.

Then for public names this A record will resolve SOME name
to the "home server". It might or might not the name "vpn" or
actually delegate the zone.

What (precisely) are you trying to accomplish? We might be
able to just tell you the method instead of helping your to
figure out some other strategy that may not even serve your
needs...
