Visited by the zero

a visitor who's IP ends with a Zero

[Hobbs]

Today I ran into this gem in my log file, a visitor who's IP ends with a Zero! 83.yy.zzz.0

The IP belongs to TELEFONICA DE ESPANA
83.40.201.0 - 83.45.92.255

It was not a bot, it requested styles.css and all images on each page, and overall did not request too many pages or exhibit suspicious behavior.

Hi Hobbs,

Because the IP range (subnet) being used is probably bigger than /24 ('class C' as was) there is nothing about the .0 or .255 in that block.

Ho Damon,
I've never seen network identifier or broadcast addresses used by visitors, very unusual, so you're saying it is legit if the subnet is larger than a class C? Hmmm

Hi,

0 and 255 are not special unless in a class C /24 block (or you happen to be at one end or another of a larger block).
