4243: DNS subscription proper fallback/valency r=disassembler a=avieth
It’s possible for the same address to be resolved from different DNS names. The subscription system now recognizes this and avoids attempting to subscribe to the same IP address more than once concurrently.
This means you can now give the same domain name multiple times in the subscription specification, and the system will attempt to subscribe to different addresses from each of them concurrently. That’s useful when we expect the names to give multiple addresses.
