Minimum globally routable address space?
- From: Dan Streufert

I am writing from a small, multi-homed ISP. We are contemplating
terminating our relationship with one of our providers, and will need to
replace that non-portable space.
We are debating between getting a /20 from ARIN (we have justifiable usage)
or a /20 from our other provider.
On one hand, portability would be nice. On the other, is a /20 globally
routable in practice? I seem to remember hearing that /19 was the smallest
that would not be filtered by anyone.
If anyone knows if there are filters for /20s out there, I would be
interested to know who filters them.
