: Filters depend on where you get your allocation. We got 216.249.16.0/20
: from arin. Since we're above the swamp, we have a greater chance of
: having any given /24 not be filtered. Shortly after we got the
: allocation, I announced a single /24, and could cleanly traceroute to
: machines on that subnet from points behind sprint, verio, C&W, worldcom,
: etc. Had we been given an allocation from 65/8 or another block in
: former-class-A space, we probably would've had problems.
You'd have to announce the /24 on a separate link and make sure traffic
came back to it. Or, stop announcing the /20. Hope this isn't insulting,
just make sure the test is good
