I've just done a bit of digging, and would this work to match an octet?
[0-9][0-9]?[0-9]?
It doesn't match 0123. Regardless, using [0-9] is destined to fail
because it will match things like 999 that also aren't an octet.

Many thanks François. This is almost right, but it is also stripping
zeros that follow a letter, and I only want it t

Hi David - thanks for that.
So [[:digit:]] is another way of writing [0-9] and the + just means another
instance of the proceeding expression, right, so your and F

Many thanks François. This is almost right, but it is also stripping zeros
that follow a letter, and I only want it to strip zeros that are proceeded
by a period. There are n

There are actually more than four examples that it needs to work on. And
more to the point, this is going to destroy any other num

I believe that should do:
sed 's/0*\([0-9]\)/\1/g'
eg.
$ sed 's/0*\([0-9]\)/\1/g

A regex would be difficult. Parser is what you want.
You could use Python's ipaddres

The first thing that came to mind is splitting the values and passing
them through printf.
(You can do it with a regex, but it's going to be one of those comical
twelve-page-long things.)
