The finest raisins of all: hysterical raisins.

Widespread consumer internet access was dialup, with Trumpet or equivalent.
The concept of "home networks" was, at best, for the uber, *uber* nerds
(like most people on this list).  The idea that an average home user would
*ever* need more than one IP was ludicrous, so your basic dialup account
provided one IP (although I recall being able to ask for more, for free, if
I needed them).  Then it became a "value add" to have more than one IP, and
then NAT came along because the hackers at home had networks, and then the
hackers at home went into IT and used consumer-grade ISPs, and so they
deployed NAT in the enterprise, and then those people became the standards
writers for PCI DSS...
