Welcome to WebmasterWorld Guest from 18.104.22.168
We have no idea how G picked up the URLs in this format (there were no links to pages with this kind of URLs).
The problem is that some pages with URLs containing the IP are ranking better than the "real" page. And of course it may harm the value of the real page as well.
We made a server side 301 redirect to the real pages but the G's index still contains around 3000 pages with the IP (together with the real pages). It seems that G did not crawled these IP-URL pages after the redirect has been set, but they are still in the index.
What do you recommend to do?
Thanks for your help!
