Welcome to the Q&A Forum

I apoligize if this question as been asked before, I couldnt' find in the Q&A though. I noticed Google has been indexing our IP address for some pages (ie: 123.123.123.123/page.html instead of domain.com/page.html). I suspect this is possibly due to a few straggler relative links instead of absolute, or possibly something else I'm not thinking of. My less-evasive solution a few months back was to ensure canonical tags were on all pages, and then replaced any relative links w/ absolutes.  This does not seem to be fixing the problem though, as recently as today new pages were scooped up with the IP address. My next thought is to 301 redirect any IP address URL to the domain, but I was afraid that may be too drastic and that the canonical should be sufficient (which it doesn't seem to be). Has anyone dealt with this issue?  Do you think the 301 would be a safe move, any other suggestions? thanks.
