rex — Reth Node Explorer

Use network node to inspect the identity and connection details that the running node exposes through admin_nodeInfo.

Command

rex network node

Example Output

NETWORK NODE

Client:          reth/v2.3.0/x86_64-apple-darwin
Node ID:         8915d6ec2f53ede650d5b9bea77d7756f177092171648ee1d8cbc550d334fa7a

Discovery port:  30303
Listener port:   30303
Protocols:       eth
Enode:           enode://44826a...@127.0.0.1:30303
ENR:             enr:-IS4Q...

The exact client string, addresses, and record fields depend on the node build and networking configuration. Rex prints - for an optional field the RPC response does not include.

How It Works

The command calls admin_nodeInfo and summarizes:

the client name and public node ID
the advertised IP and listening address
discovery and RLPx listener ports
supported application protocols
the enode URL and Ethereum Node Record, when present

The node ID identifies the devp2p participant. It is not an Ethereum account address, transaction hash, or execution block hash.

admin_nodeInfo is read-only, but the surrounding admin namespace is sensitive. Expose it only on a trusted interface.
