Access mydomain.com (shared hosting) while in network mydomain.com

[Guest]

Hello,

The domain at our office is called mydomain.com. We just setup our website
on a shared hosting site, where we use a shared ip. That side is authortative
for our domain name.

Outside of the office we can access mydomain.com ok, but inside the network
we can't.

I don't want to delegate the internal dns function to the external website,
so how do I create a situation where when one types in www.mydomain.com the
site can be accessed within the network?

Or should I get a dedicated IP?

Hello,

The domain at our office is called mydomain.com. We just setup our
website on a shared hosting site, where we use a shared ip. That side

Outside of the office we can access mydomain.com ok, but inside the
network we can't.

I don't want to delegate the internal dns function to the external
website, so how do I create a situation where when one types in
www.mydomain.com the site can be accessed within the network?

Or should I get a dedicated IP?

Common scenario with an easy fix.

Two choices:

1. Obtain the IP address of the external web server. Then under your
mydomain.com zone, right-click, new Host, type in www (without the quotes),
and provide the IP address you obtained. To allow users to get to it using
http://mydomain.com (without the www portion), on your DC and every DC (this
is because of the LdapIpAddress, or the 'same as parent' record), go into
IIS, under the default website properties, home Directory tab, setup a
redirect to www.mydomain.com.

2. Find out who the external authorative name servers are for the domain.
Then right-click your internal zone mydomain.com, New, Delegation, then
provide it with a www, then for the name servers, provide the authorative
name servers you obtained. This will allow for the hosting company to
occasionally change the webserver's IP address and you will still get to the
site. Yea, some ISPs do that and don;t tell you. You will also need to do a
redirect to make http://mydomain.com work.

btw- the name blinton sounds like a guy I know. Are you from the Philly
area? If not, sorry, it's just a coincidence.

Hello,

Sorry, not from the USA, but hope you are able to track down your friend
though.

Just to confirm, even though the hosting company hasn't given me a dedicated
IP, I should still be able to access the server by specifying the shared IP
using www?

Before you delegate, run nslookup www.mydomain.com 4.2.2.2
This will return the record for your external web site, if this record is a
CNAME pointing to mydomain.com the delegation won't work, however, if it
returns www.mydomain.com as a CNAME pointing to someotherdomain.com, you
need only create an identical CNAME record in your internal DNS.
In all likelihood, since your hosting provider is using a shared IP,
www.mydomain.com would be a CNAME. I had a user a couple of weeks ago that
their external host had a CNAME that pointed to a CNAME, that pointed to
another CNAME. You need only create the first.

I've been seeing issues with 4.2.2.2 lately. Youmay want to try:

nslookup www.mydomain.com 4.2.2.3

Hello,

I got the following:

C:\Documents and Settings\User>nslookup www.mydomain.com 4.2.2.3
Server: vnsc-lc.sys.gtei.net
Address: 4.2.2.3

Non-authoritative answer:
Name: www.mydomain.com
Address: 64.15.146.78


C:\Documents and Settings\User>nslookup www.mydomain.com 4.2.2.2
Server: vnsc-bak.sys.gtei.net
Address: 4.2.2.2

Non-authoritative answer:
Name: www.mydomain.com
Address: 64.15.146.78

www.mydomain.com appears to be an A record, so a delegation will work fine.
