Ok, this problem is fixed. We had an error in the lookup server LC-trie where we didn't properly lop off all the bits of the netmask.

No Firefox Extension update is required as this information is entirely server generated and the fix has been applied there. -- Andre > -- > Andre > > > Karsten > > > > > -----Original Message----- > > > From: Andre Oppermann [mailto:[EMAIL PROTECTED] > > > Sent: Monday, February 13, 2006 2:37 PM > > > To: swinog@swinog.ch > > > Subject: [swinog] ASNumber Extension for Firefox [LNC-Admin > > > SPAM][bayes] > > > > > > > > > We've written a Firefox Extension that displays the AS Number of every > > > website visited along with some additional interesting > > > information.
