```bash Sigma Prime contact@sigmaprime.io Simple CLI tool for starting and debugging discv5 servers. This currently runs a discv5 server which regularly performs peer search queries

USAGE: discv5-cli [FLAGS] [OPTIONS] --listen-address --listen-port

FLAGS: -w The Enr IP address and port will be the same as the specified listening address and port. -h, --help Prints help information -k, --static-key Use a fixed static key (hard-coded). This is primarily for debugging. -V, --version Prints version information

OPTIONS: -e, --enr A base64 ENR that this node will initially connect to. --enr-address Specifies the IP address of the ENR record. Not specifying this results in an ENR with no IP field, unless the -w switch is used. --enr-port Specifies the UDP port of the ENR record. Not specifying this results in an ENR with no UDP field, unless the -w switch is used. -l, --listen-address Specifies the listening address of the server. [default: 127.0.0.1] -p, --listen-port Specifies the listening UDP port of the server. [default: 9000] ```
