Given the small netmasks, I'd guess that most of the browser population
behind them is addicted to a proxy. The proxy might not subscribe to
pinning. 

Also, the browsers that run for months typically aren't on end-user PCs,
but on the workstations of the clued, if I might be so blunt. 

It is not that renumbering is painless, not at all. But it is very useful
as "spring cleaning". I'd rather know what happens by testing it than
finding out by being woken up while on call.
