DNS round robin

Hi all,

I'm new to technology and will need your expert advise to complete my task step by step

I need to create a internal site in two different 2012 servers in IIS (using dns round robin) and not sure how to do this. site will only be accessed internally. IIS is already installed on both servers.

server1 is with IP 10.x.x.1
server2 is with IP 10.x.x.2

what do I need to do this task please can you advice?

Open DNS manager, shown below. Go to properties of DNS servers, go to advanced Tab and check mark on Round Robin option.( By default it’s enabled).

Now Create the two "A records". as shown below.

YourSiteName 10.x.x.1
YourSiteName 10.x.x.2

Now restart the DNS service and you are good to go.

if it not works immediately then run "ipconfig /flushdns" and then "ipconfig /registerdns" and check

DNS Round Robin is a mechanism of load balancing but it is not load balancing in itself. You will need to use something like WNLB (Windows Network Load Balancing) or a hardware load balancer. I suspect because this is a simple IIS server WNLB would be fine to setup.

Configure WNLB

thanks guys. I am confused with one thing

is this A records same as the server IPs? Because IPs that assigned to the site is additional spare IPs

I've given these IP addresses basically

server1 IP =10.x.x.1 10.x.x.2 to use for the site ( this is additional IP on the server)
server2 Ip =10.x.x.3 10.x.x.4 to use for this site ( this is additional IP on the server)

Hi,

Why are using such spare IP?? having secondary IP on the same subnet will cause some problems

Thanks Salah,

I would use NLB not even DNS Round robin but this is what I've given to work with and approved.

What problems are talking about? I would still carry on what I have unfortunately.

thanks

Hi,

It depend on how you configure the additional IPs, is it on the same interface? in this case I could not figure out the need !! if it's in different interface this will cause a problem as the TCP/IP stack will get confused on how to send traffic.

Best regards.

I think idea was to separate host traffic and site traffic. All I can see is one NIC network connection settings with spare IP for the site to use.

So Can you please give the instructions?

thanks

Hi,

What's the NIC speed? basically you will access the IIS server from inside I guess the host trafiic will be only server management!!

honestly not worries about the speed, it is on hyper V host so I am assuming it is all taken care of.

I am only worries for the records for now please. Do I also need Cname record in AD?

thanks

Hi,

Since you will use the sites for internal context, you can only have the A records!

Best Regards.

server1 IP =10.x.x.1 10.x.x.2 to use for the site ( this is additional IP on the server)
server2 Ip =10.x.x.3 10.x.x.4 to use for this site ( this is additional IP on the server)

whatever ip you are using as primary. you should create the HOST Record (YourSiteName) with the same IP which is assigned to your server1 and server2 (website hosting).
