Multiple IP address for domain name


We have multiple lines coming into our building with static IP addresses.  We recently experienced an issue with one of our lines.  Given we have two lines with multiple static addresses is there something we can do with DNS that allows multiple routes into the network. We have web facing applications that are open on specific addresses, for example pointing to IP address, I can open the service up on multiple IP addresses on different lines but I am unsure how I can route a web address to multiple sources.

Is there a simple way to route to two IP addresses or a service that sits in the middle that can send to two different ip addresses we can control ?

Unfortunately this is not easy to do unless you actually own the public addressing that's used. DNS has no way to know whether an address is up or down, so it will keep responding to requests and giving out addresses that may or may not be good.

You could find a 3rd party provide what is essentially a load balancer service for you, which would constantly monitor ip address availability and forward to the available address. Then your DNS would always reply with THEIR address and they would send traffic to a working address.

It might be easier to simply host your web services elsewhere, because then they keep the network functioning and you can just maintain your application there. You can work with a good hosting provider to maintain any back-end connectivity. I always recommend SiteGround because they have really excellent technical support and their services are top-notch.

DNS can be used for load balancing, but not redundancy.

If you configure 4 IP addresses for one URL, then DNS will "round robin", giving each address out in sequence, when queried. Assuming a large number of clients, the load can then be shared over the 4 addresses.

If one is down, however, DNS will still hand out that IP 25% of the time, meaning a quarter of all clients will not get through.
