Actually, I've been using pooled /20 subnets for years, which was
considered best practice for campus networks at the time it was
implemented. Roaming to a new subnet never happens.

This made me go look up the current best practices though, and it appears
that the pooled model is being deprecated in favour of bigger subnets. Good
