Adam Schmideg	6a48ae37b2	cmd/devp2p: add discv4 test suite (#21163) ... This adds a test suite for discovery v4. The test suite is a port of the Hive suite for discovery, and will replace the current suite on Hive soon-ish. The tests can be run locally with this command: devp2p discv4 test -remote enode//...

Felix Lange	b7394d7942	p2p/discover: add initial discovery v5 implementation (#20750) ... This adds an implementation of the current discovery v5 spec. There is full integration with cmd/devp2p and enode.Iterator in this version. In theory we could enable the new protocol as a replacement of discovery v4 at any time. In practice, there will likely be a few more changes to the spec and implementation before this can happen.	5 years ago

Felix Lange	0568e81701	p2p/dnsdisc: add implementation of EIP-1459 (#20094) ... This adds an implementation of node discovery via DNS TXT records to the go-ethereum library. The implementation doesn't match EIP-1459 exactly, the main difference being that this implementation uses separate merkle trees for tree links and ENRs. The EIP will be updated to match p2p/dnsdisc. To maintain DNS trees, cmd/devp2p provides a frontend for the p2p/dnsdisc library. The new 'dns' subcommands can be used to create, sign and deploy DNS discovery trees.	5 years ago
Felix Lange	896322bf88	cmd/devp2p: add devp2p debug tool (#19657) ... * p2p/discover: export Ping and RequestENR These two are useful for checking the status of a node. * cmd/devp2p: add devp2p debug tool This is a new tool for debugging p2p issues. It supports a few basic tasks for now, but many more things can and will be added in the near future. devp2p enrdump -- prints ENRs readably devp2p discv4 ping -- checks if a node is up devp2p discv4 requestenr -- gets a node's record devp2p discv4 resolve -- finds a node through the DHT	5 years ago
