<B>Asunto</B>: To varnish sysadmin: Blocked IPv4 Space 50.0.0.0/8<BR>
<B>Fecha</B>: Tue, 16 Nov 2010 12:57:08 -0500<BR>
<BR>
Hi all,<BR>
<BR>
First i want to thank to all you for this great app. We use varnish in all our website projects.<BR>
<BR>
I have only one issue, we used to install varnish binaries on Debian Lenny using backports.debian.org. But we are migrating to the official varnish repo for obvious reasons. My new servers have addressed the elastic IP's from 50.0.0.0 range. But i can't access your repositories from 050/8 address.<BR>
<BR>
All my servers are deployed in amazon EC2, recently IANA has given the Network 050/8 to ARIN (see <A HREF="http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xml">http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xml</A> ) and Amazon brought some on the IPv4 Space 50.0.0.0/8, for unknown reasons i cant access your IPv4 adresses; it seems that you have the IPv4 Network 87.238.36.96/27 or at least some IP's bettween 87.238.36.97 and 87.238.36.126.<BR>
<BR>
Surfing on the net there are some references of system administrators whose have blocked the 50.0.0.0/8 pool. Probably it was used to botnet activities and/or IP Spoofing. But now there is no reason to block. IANA assigned these addresses in 02/2010.<BR>
<BR>
I have tested several IP's of Redpill Linpro AS (it seems like your Hosting Provider) and mostly of them works, but varnish related (deb trac planet www) IP's doesn't work. As you know there are a huge of users in amazon EC2 using Varnish. It will be a problem to all of them.<BR>
<BR>
I'm not saying that the blocking is in your servers. But all my tests appoint to that. Please help us with that.<BR>
<BR>
PD: Please forgive me if my English is not polite. Spanish is my natural language.<BR>
<BR>
Regards,<BR>
