That's how Verio does it, and I assume, that's how most people who
filter by length do it as well.

Good question.
You know there are thousands of legacy /24's out there that were
allocated by
IANA as /24's How can you aggregate them up if all you have is the /24?
To those who filter out /24's - how is this done - just by the netmask
size?

Subject: Pitfalls of annoucing /24s
In current practice would there be serious jeopardy of portions of the
internet not being able to reach this address space due to bgp
filters or
other restrictions? What is the smallest acceptable block of IPs that
can be
announced without adverse or unpredictable results? Verio would most
likely
be picking up these routes from us. I don't want to cause a religious
debate, but I am interested in what the industry consensus is.
I'm just doing some research, any comments would be appreciated.
Thanks,
Jean-Christophe Smith
