Could also set up DNS server to return different IP addresses for same hostnames depending on the which interface the DNS client is connecting from. There'd only be one hostname per server, two (or more) IP addresses each mapped to originating network.

- HvTfMhdTZ8Lths6 4y agoI don't think it's reasonable for clients to cache responses across disconnect/reconnect, especially when the network has observably changed (new default gateway, for example), and even more so when the resolver has changed. Based on my own personal experience I'd also say that no (modern) clients do so although that could be wrong.
