Optimization: Keep Connection to Remove DCUtR peers alive

• track identify messages and look for changes in advertised relay addresses

I assume you mean "remote" DCUtR peers? Just to help my understanding, could you briefly explain why this is needed?

[mxinden]

The optimization is meant for the honey pot, not for the hole punching clients.

Keeping the connections to the (potentially behind a firewall) remote peer alive, as the honey pot, also keeps the identify protocol stream to the remote alive. Keeping the identify protocol stream alive implies receiving identify updates, in particular new relayed addresses, from the remote peer.

Does that make sense? Happy to expand on the reasoning.
