testdhcpv6pd

Sends a DHCPv6-PD solicit message and displays the response (no request is done)

usage:

testdhcpv6pd [options] [interface name or index]

  -a string
    	anonymize ip addresses (format = list word indexes to show) (default "12345678")
  -cid string
    	specify client ID (DUID-LLT) using a mac address ( : or - separated digits)
  -cll string
    	specify client layer address using a mac address ( : or - separated digits)
  -p string
    	ask for a specific prefix and/or length (default "::/64")
  -s	dont print debug messages
  -v	display version

Without argument, testdhcpv6pd will display the available interfaces

Use -s to suppress packet debugging

Use -a format to anonymize the prefix where format is a list of indexes. Each index, from 1 to 8, is the part number of the address to keep. For instance -a "18" only keeps the first and last part of the address.

Use -p ::/60 to request a /60 prefix or even -p 2a01:xxx:xxxx:xxxx::/64, to request a specific prefix

Use -cid aa:bb:cc:dd:ee:ff to change the DUID (LLT format, RFC 8415 Section 11.2). Format is a MAC address, : or - separators.

Use -cll aa:bb:cc:dd:ee:ff to add a link layer address option (RFC 6939). Format is a MAC address, : or - separators.

notes

Not tested on *bsd, plan9

Linux systems require at least cap_net_bind_service capability to bind to port 546 (see man 7 capabilities) or just use sudo

Darwin/MacOS: use sudo
