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

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
