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