Oliver & Kris,

Thanks much both of your responses were very helpful.  I have decided to
subclass PGobject to address the issue and have created a PGcidr class which
seems to be working well.

If there is any interest in adding this to the project, I would be happy
to submit what I have for review and also provide PGinet and PGmacaddr classes
to the core.

Thanks again,
Russ
