No.
If they did, 80% of the internet would not be visible to them today.,

Subject: Any people still with old filters?



In a recent discussion with a company that owns a /16 and has it broken
down further, the statement was made that there are ISPs that filter
routes at /16 in what was traditional class B space.  The example cited
was Verio.  Verio web pages state they don't do this any more (the
filter is /21).

Is there anyone that still filters routes longer than /8 and /16 in the
traditional Class A and B space?
