Hi All,

I found my weblog contain entries like 121.23.3 Instead of four octet.
I am quite confused is it possible to have 3 octet ip at all ??
Is it generating by any program and hittng the website ?
Is it a subdomain ?

Please tell me your understanding on it ?

Thanks

Must be a bug or something. IPV4 is a 32 bit address and there's no way to leave some bits out.

Sounds like it's refering to a class C subnet (ie 121.23.3.1 - 121.23.3.254). See if there's a netmask associated with it someplace...

You could try posting a snippit of your weblog (might want to replace any sensitive data with ***'s or something first though). Also naming the webserver creating this would help narrow things down too :wink:

I'm guessing the log simply got truncated (if you mean an Apache access log).

Thanks all for helping me out.

This is a apache weblog file only.
Weblog format some thing like
IP - - [Time stamp:GMT] "Requestor string" statsus Size(bytes) "Referral URL" COOKIE_INFO="...................."

I will post a exact log record tomorrow.

But i am clue less how a 3 octet IP coming into this log file , When it is not at all possible to have a ip like in IPV4 as mentioned by Perderabo.

Not a single record -- So many record of the log contain 3 Octet IP.

  • If we are talking about the apache truncation ???why other ip are 4 octet .. it should either truncte all ip to 3 octet or leave it at was .--Right ??

I googled out this ,,but no idea in what scenario one can see 3 octet ip in web log .

Please keep posting if any one has any information on this- the answer to the mystry will be a great relief for me .

Thanks
