Good tool, does what it says on the tin and being command line driven means you can pass in a list of IPs and parse the results. Passing IPv6 addresses via pipe

Good tool, does what it says on the tin and being command line driven means you can pass in a list of IPs and parse the results. Passing IPv6 addresses via pipe threw errors for me but xargs was an easy workaround. Normally I’d use the subnet calculator on MXToolbox’s website for convenience but it doesn’t support IPv6.
