The other weekend I wrote some notes on how to quickly spin up an IPv6 test lab<\/a>. The idea for this was to allow me to write a custom tool to enumerate hosts that respond to IPv6 neighbour discovery on my local network. I then wanted that tool to identify the corresponding IPv4 address for that host (if there is one). And finally, identify if the IPv6 address is a router as it responds to Router Solicitation requests.<\/p>\n

\"\"<\/a><\/p>\n

I wanted to do this with minimal dependencies, the only one currently is arp-scan, however there’s the likelihood that I can remove this dependency by coding it manually in the future. I’ve purposely not coded with RFC4862<\/a> in mind as SLAAC (Stateless Address Autoconfiguration) as some devices such as OS X<\/a> adhere to RFC4941<\/a> and randomise the link local address as a privacy feature.<\/p>\n

Another thing I wanted to ensure was that this tool worked on both OS X and Linux, so I’ve tried to ensure that’s the case.<\/p>\n

I’m not one for writing much, so here’s an example run as a picture describes a thousand words:
\n\"\"<\/a><\/p>\n

One thing to note, this works for IPv6 to IPv4, if the host doesn’t have an IPv6 address it won’t be shown in the list…<\/p>\n
