This rule fires on traffic from the Akamai IP block 23.0.0.0 - 23.15.255.255, which appears to be legitimately assigned, and not at all uncommon. (brett@wrl.org)

This rule fires on traffic originating from Akamai ( 23.0.0.0 - 23.15.255.255) which seems to be legitimately assigned to them.

It shouldn't, that net isn't included. Are you running the most current revision?

I am unsure why this rule is triggering the attached packet but the attached packet is from the host 199.17.22.168 to my $HOME_NET and I don't see how the source host fits into the alert. In any case I don't believe it should fall into the Bogon Nets space.

-- BenPratt - 09 Apr 2009

I'm not sure why that hit. It certainly isn't included in the IP space listed. Did this just happen once?
