Hi Steve,

That's like saying the inverse mask is technically correct when the
computer wants to decide whether to arp for the next hop. No sale man.

A AND NETMASK ?= B AND NETMASK

is exactly the same operation as

A OR inverse NETMASK ?= B OR inverse NETMASK

While A AND inverse NETMASK ?= B AND inverse NETMASK *never* yields
useful knowledge.

No sale.
