Those are nodes from the Flux (previously named ZelCash) network. It’s a code fork of Zcash, in which they did not alter the network magic, ~~default port~~ , or user agent. I think the reason these are appearing in that explorer view is because these nodes were connecting half-successfully to `zcashd` nodes (their handshakes succeeded, but block propagation didn’t), causing them to be cached in the `zcashd` nodes’ `peers.dat` files. After NU5 activated, these nodes were disconnected from, but there’s a bug in `zcashd` where when it receives a `getaddr` message, it will return peer data from any peer it’s connected to before, not just peers that it would currently try to connect to. > > > \### Describe the issue > > While debugging an issue with our DNS seeder, I found …some Zcash 5.0.0 nodes that are returning Flux nodes in their \`addr\` responses (old protocol version, 170018 IIRC, and port 16125). > > \### Can you reliably reproduce the issue? > \#### If so, please list the steps to reproduce below: > > You could use our \[DNS seeder\](https://github.com/ZcashFoundation/dnsseeder), and I can also privately report some IPs that have this behaviour if needed.

Everything is clear, thank You! ---

Ah yes, I forgot about that. Sadly that’s insufficient (and not intended) for use as a filter, since it’s fine for Zcash full node operators to use whatever port they want. The P2P protocol version will suffice for now, and if it becomes more of an issue later then we can try and craft a filter.
