Hi Ben,

oh, thank you, I don’t have any of these systems around at the
moment, so checking them was tricky for me.

So basically I should read an int in host endianness then (or
keep the code I currently have that compares byte 0 and 3, using
the one that’s not 0, if any). Great, thank you!

After some minor porting work, it turns out that the current code
does work on MidnightBSD (equivalent to FreeBSD 10.4) for IPv6.
I guess I’ll keep ints then.

bye,
