IIS site set up

Hi, I'm new to IIS and need your help please. Sounds easy so apologies for being newbie.

I have 2012 server with manually assigned IP and also lots of additional IP addresses assigned to it for all the sites. Server is currently hosting more than 10 sites on it.

one of the site is no longer needed and I need to release redundant site's IP and assign it to new site will be hosted on the same server.

What would be correct process please? IP that is assigned to redundant site is in the Ipv4 settings from network adapter properties and when I click on the "advanced" I can also see all the other IPs in the list  which are in use.

do I just need to request for "a" record for "siteA" pointing to IP that is I need? ( in that case when I do nslookup it will be showing me the server name and the siteA?)

To assign the redundant site IP to a new site,
Stop the redundant site
Bind the redundant site IP to the new site by configuring the header for the site in IIS Manager
Configure you DNS to point to the new site; IP address to point to the new site i.e

I hope this helps.

Thanks emmanuel,

did not understand that very well, what about the "A" records? can you send me some screenshots? thanks

also would that not cause any issues to server if we need to change DNS ? IP is normally resolving to server name at the moment? thanks

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Does each site on the server resolve to it's own IP address? If yes you need to configure the new site to resolve to the IP address in your DNS and this should not cause any issues to the server.

when i do  ---> nslookup---->set qtype =a ----->site1  or site2 each of the sites resolves its own ip assigned to them which is in the NIC properties. This is where I got confused.

I'm also trying to learn hpw IIS works so if you can please provide more info I would be really happy. thanks for your time

That's fine, this means that each site is binded to an IP.  So you will need to configure the new site and assigned the old site ip address and set up the DNS A record.

so steps are:

stop the old site
remove a reecord for old site in dns
create a new site
create new a record for new site
bind site to that IP in IIS
?
Emmanuel AdebayoGlobal Windows Infrastructure Engineer - ConsultantCommented:
I would do it this way

 Stop the old site
 Create a new site
 Bind site to the IP in IIS (Using the IP address of the old site) with host header
 Test (Add the IP address Sitename to your workstation hosts file and browse to Sitename from your workstation)  
 Remove A record for old site in dns
 Create new A record for new site
