4294967040 expressed as a hex number is FFFFFF00.

3232236032 expressed as a hex number is C0A80200 which is expressed in IP format (are you sure that last octet is 3?).

I suspect your MAC addresses are simply 48 bit binary values, which may cause a little trouble if you are using a 32 bit Perl without native 64 bit integers, but only a little trouble.

Maybe if you had cared enough about the problem to format your node I'd have been enthusiastic enough about it to help further.

Perl is environmentally friendly - it saves trees
