how to run a discv5 node:
go build ./cmd/devp2p
./devp2p discv5 listen -nodekey ... -addr 127.0.0.1:9000

Version 5.1 is currently in a PR at this repository in the version-5.1
branch. Once it interops it will be merged down. Its in between different 5.1 versions currently.
To a run node, which periodically sends FINDNODE requests:
cargo run --example find_nodes -- 127.0.0.1 9001 false
NOTE: This will still bind to 0.0.0.0 but the ENR will display 127.0.0.1. You can set this to your local/external IP to modify the ENR emitted. It will listen on 9001. The final boolean indicates if you want to generate a random node_id. false indicates a fixed hard-coded id for debugging.

Version 5.1 is in a PR, branch is discv5-v1
: https://github.com/status-im/nim-eth/tree/discv5-v1
You can use the dcli
tool to test:
# Install required modules
nimble install
# Build dcli, v5.1
nim c -d:chronicles_log_level:trace -d:release -d:UseDiscv51:true --threads:on eth/p2p/discoveryv5/dcli
# Run it, e.g.
./eth/p2p/discoveryv5/dcli --log-level:debug --nat:extip:127.0.0.1 --bootnode:enr:<base64 encoding of ENR>
# Just ping another node
./eth/p2p/discoveryv5/dcli ping enr:<base64 encoding of ENR>
