heads up on 80/8 [actually operational, so don't read this!!!]

In the referenced message, Sean M. Doran said:

Hello, long time no see -

RIPE is now allocating subnets of 80/8 to end users.

In order to avoid the ugliness of various people announcing 80/8
without guaranateeing transit to all the subnets, if you are filtering
subnets of this /8, please relax your filters to allow /20s and shorter,

On behalf of random Europeans,

  Sean. (yeah, ok, this is at least partially work-related-stuff...)

According to
They are also allocating out of 81/8, so if you want to avoid making changes
to filters twice, may want to add that as well.
