Good question. You know there are thousands of legacy /24's out there that were allocated by IANA as /24's How can you aggregate them up if all you have is the /24? To those who filter out /24's - how is this done - just by the netmask size? ----- Original Message ----- From: "Jean-Christophe Smith" <jsmith@vitalstream.com> To: <nanog@merit.edu> Sent: Wednesday, October 15, 2003 15:34 Subject: Pitfalls of annoucing /24s
In current practice would there be serious jeopardy of portions of the internet not being able to reach this address space due to bgp filters or other restrictions? What is the smallest acceptable block of IPs that can be announced without adverse or unpredictable results? Verio would most likely be picking up these routes from us. I don't want to cause a religious debate, but I am interested in what the industry consensus is.
I'm just doing some research, any comments would be appreciated.
Thanks, Jean-Christophe Smith
