IP dns question

[GriffithsJ]

I have a series of websites, let's call them "customer1.mydo main.co.uk" -->
"customer200.my domain.co.uk".

Each URL is bound to an individual IP address which can be resolved using
nslookup.

So, for example
customer1.mydom ain.co.uk = 100.200.300.1
customer200.myd omain.co.uk = 100.200.300.200

However, I can't fit all these 200 websites on the same server, so I have
bought 4 servers, serverA -> serverD.

I have arbitrarily put customer 1-50 on serverA, customer 51-100 on serverB
etc.

Having set all this up, I now find that customers 1-50 represent most of the
load, so I want to distribute the load a bit more evenly. You can imagine
the scenario.

As part of my Admin tools, I've created a display that does dynamic lookups
of the URLs and returns me the IP address from the DNS A record. However, I
want to have some way of finding out which machine this IP is actually bound
to. I'm constantly migrating dealers from one server to another and keeping
track of this manually is too great a headache. Does anyone know of a
method of saying "I've know the web site address by a) the URL and b) the IP
address, I now need to find out the name of the server on which it is
bound". Each server has a primary IP address that is "permanent" and not
associated with any customers' web site.

Any ideas?

Thanks

Each time you add an IP to one of your servers
dump an updated list of IPs bound to the machine.
In your mgmt code, use the four lists as x-ref lookups.

You're probably going to catch hell for this post since you posted to
microsoft.publi c.windows.serve r.dns
microsoft.publi c.win2000.dns
microsoft.publi c.scripting.vbs cript
microsoft.publi c.vb.general.di scussion
microsoft.publi c.inetserver.as p.general
microsoft.publi c.inetserver.mi sc

Unless your web servers are running on W2K, this does not have anything to
do with:
microsoft.publi c.win2000.dns

These definitely do NOT have anything to do with DNS:

microsoft.publi c.scripting.vbs cript
microsoft.publi c.vb.general.di scussion
microsoft.publi c.inetserver.as p.general

This one really doesn't either but it is server related:
microsoft.publi c.inetserver.mi sc

That leaves us with this;
microsoft.publi c.windows.serve r.dns

It is also not really a DNS question since it is a philosophy or methodology question related to host name naming practices. It should fall more into
the security arena because adding the server name to your URL is a security issue. Your servers should be behind firewalls. Your internal DNS can have anything it wants but external should only have public domain naming.

Please only follow up in m.p.window.serv er.dns
