I have a server that hosts IIS websites. Each website has a different IP. In order for the IP to show up for selection in IIS, I've bound each IP to the network interface (which now has multiple IPs instead of just the one server IP). The server does not have multiple NICs, so they all need to go on the single NIC present.
My question: Internal DNS automatically registers all IP addresses assigned to the NIC. However, the server is only supposed to respond (as a server) on the primary IP. Can I safely remove DNS registration from the NIC altogether and only add the single primary IP to internal DNS, while still keeping IIS working properly with its websites on other IPs?
