Are numbers larger than 0xff even possible?

We read the string from "/proc/net/if_inet6", and to me it looks like
the interfaces limits the input range to values <= 255 [1].

Would be great if you could provide an example where it really makes a
difference, i.e. how to get lager values than 255 in the ignored format
string positions.
