Re: Verisign abusing .COM/.NET monopoly, BIND releases new

This is simply amazing, Verisign has just turned the .COM and .NET TLD
DNS servers up-side-down for their own economical gain and, in doing so,
disrupted network traffic for most of the Internet. Mail administrators
who use any non-existant DNSBL to mark email as spam suddenly has all
their mails deleted, people using localhost.localdomain.com on their
servers for administrative purposes are scrambling to find out the cause
of their problems and DNS problems arise everywhere as neg caching is
essentially disabled and all DNS caches have to cache each and every
randomly typed DNS query.

The BIND patch that prevents this should be released Wednesday.

I hate to muck with a DNS server to fix this problem.  And since
I prefer DJBDNS, a BIND patch wouldn't do me any good anyway.

Is it always returning the same IP address, or have any other
noticable characteristics?  If so I'd think we could set up
a firewall rule to drop all DNS replies that contain the
Verisign-be-damned IP address.  That'd protect everything,
regardless of name server or method of access (using
host/nslookup/etc manually.)
