There are plenty of folks who have space in 64/8. However, no one should be classfully advertising 64.0.0.0/8, as it has not been assigned to any single entity. Therefore, anyone who is advertising this block is doing so in error, and it's permissible to filter the EXACT 64.0.0.0/8 route announcement. (as opposed to filtering "64.0.0.0/8 or longer", which would blackhole many folks) - Daniel Golding -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu]On Behalf Of Shawn McMahon Sent: Tuesday, February 27, 2001 6:25 PM To: nanog@merit.edu Subject: Re: 64.0.0.0/8 etc. [was: Re: BGP Question - how do work around...] On Tue, Feb 27, 2001 at 08:01:46AM -0800, Christian Nielsen wrote:
For 64.0.0.0/8 this seems to have happened in the meantime... but now there's a route for 62.0.0.0/8 (the RIPE equivalent of 64.0.0.0/8),
sigh.
i dont know why you even allow 64/8 and/or 62/8 into your network. Filter them...
Aren't many Earthlink dialups in 64/8? Filtering that would mean his employees couldn't get Sprint DSL, and prevent millions of potential customers from reaching his web servers. That's not smart business. It's called "cutting off your nose to spite your face."
