New ip class for googlebot ?

193.235.238.233

[adresanet]

Checking my logs I saw some agents called Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html) having 193.235.238.233 and 193.183.67.228 ip. Not the usual 66.249.xxx.xxx

Are these ips real or are fake ?

[Pfui]

Not Google. They're fakers from Swedish-based Internetbolaget Hosting.

Many sites will tell you the details about IP/Hosts. I find this site handy: [myip.ms...]

(Paste one of the IPs you asked about into the site's upper right box for more info.)

If you use a Unix/Apache server, you may wish to consider filtering out all the fakers by only allowing verified Google crawl ranges with an htaccess rewrite rule similar to this:

RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} Googlebot [NC]
RewriteCond %{REMOTE_ADDR} !^66\.249\.[6-9][0-9]\.
RewriteCond %{REMOTE_ADDR} !^74\.125\.
RewriteCond %{REMOTE_ADDR} !^173\.194\.
RewriteCond %{REMOTE_ADDR} !^203\.208\.[3-6][0-9]\.
RewriteRule - [F]
