Why is my IP address in Google's search results?

[wchan07]

i recently did a search of "mydomain.com" and found my ip listed. I did a "site:xx.#*$!.xx.xx" for my ip and found that there were 7,000 pages indexed with my IP as the url.

Is this normal? i am not aware of any link that is pointing to my site by IP. Is someone trying to junk my site somehow by getting google to index my site under different urls and trick it into thing there is a dup site?

Can anything bad happen b/c of this? I figure google will know that my ip and domain are the same site and that nothing will happen but i wanted to make sure.

I have done "site:ip address" of random big sites and i do not see other ppls web pages being listed by ip instead of their normal url.

i have block access to my site by ip so i am guess this should stop. Just wanted to check if this is malicious or normal.

You now have Duplicate Content issues.

The solution is a 301 redirect to the canonical version of the domain that you do want to be indexed.

Do not simply block access via the IP address. Now that you have people clicking those IP results in the SERPs to come to your site, you don't want to block them. Use the redirect instead.

I covered this about a month ago in several posts. One of those is at: [webmasterworld.com...]

I've had the same problem in the last few days, where listings by IP address have replaced my domain name listings for some search results. It's a 5-year old site which has had consistently good rankings (pagerank 4 / 5). Now some of my listings have slumped or vanished.

I've put a 301 redirect in place. My question is, should I do anything else? Submit a reinclusion request, for example? Has anyone had experience of how long it can take to clear up the problem? And is Google's perception of my website likely to be permanently harmed?
