      Hello ,

I want to ask about PI assigned address space.
The best example is my own one which good show us bad idea of assigning
exactly size than user require..

Today we got very bad organisation in world BGP table.. a lot of bad
aggregated prefixes etc.. so carrier providers from day to day 8-)
move filter mask to right... now ie. Sprint:

http://www.sprint.net/policy/bgp_filters.html:
[...]
Customers may announce routes as small as /26 for IP address blocks obtained through Sprint.
Announcements for blocks obtained from other providers are limited to a /24 or smaller mask (/23, /22 etc.). This applies only to Sprint customers; peers are bound by a much stricter prefix policy.  
[...]

so if RIPE will assing PI requests addresses exactly as written in ripe-141
from we give our clients big chance that they will be filtered.
The of course aware about it .. but.. when we have /24 we got 70% chance to
filtered with.... ie. /26 we got 40% and less..
so it can effect in one bad situation..
ripe forms written for PI assign policy and requests of /24 or smaller for
route security and out customers become unhappy...
IMHO one way is change our LAW to be good for mass not for goverment only 8-)
so i please you to made some updates and assign PI depend on actually
known filtered size in carrier networks... in europe and whole world

PS: sorry for my bad english and grammar 8-|

here is some sentences from ripe-127 8-)

thank you!

                ments  etc..   This  also  implies that assigning PI
                space prefixes longer  than  24  bits  is  perfectly
                acceptable  if  the request does not merit 8 bits of
                address space to be assigned.

                     Assignment of this address space is  valid
                     as  long  as the criteria for the original
                     assignment  are   still   met.    However,
                     assignment of address space does NOT imply
                     that this address space will  be  ROUTABLE
                     ON   ANY  PART  OF  THE  INTERNET.  It  is
