It is the integer hexadecimal value of the address of the pool
structure in virtual memory.

It's the only way to determine the difference between multiple
pools in a single subnet over the span of a given runtime; the address
in virtual memory will change but the covering subnet won't, so you'll
get a bunch of log lines for e.g. 140.211.162.0/26 if it had more than
one pool.

Don't shoot the messenger; it was like that when I got here.  If I
had it do to over, I would use any random dynamic address from the
pool as a unique identifier for the pool, like the first address in
the first 'range' statement.
