I have yet to read any postings where someone was banned because of something done by another web site on a shared IP. Is the IP address really an urban myth?

Just in case the virtues of a private IP is real what happens when a site is moved from a virtual host to a private IP address? How does that impact serp? Is there a change that SE's will recognize the change and give whatever advantage there is to having a private IP?

If you would like to see if your IP has been banned by Google first go to MSN and type in the IP address for your site: 'ip:nnn.nnn.nn.nn'. Then go to Google and do a search for: 'site:www.example.com'. If the page links appear, then the IP has not been banned--(you may to do a few sites because, as you know, not all sites make it into Google.)

What do you mean by "getting banned"?

I once had (temporary) problems because an ISP was using one of those spam clearinghouse "kill a fly with a ballpeen hammer" sorts of "services. My sister couldn't receive mail from my mail account for a couple of weeks because some other site hosted on the same server as mine had been accused of sending spam.

Is the above what you meant, or are you referring to something else?

Thank you.

Banning because of spamming is definitely part of the issue. It makes sense that your IP got a black eye from one misbehaved rascal. And that your SE placement would be impacted because your site could not be spidered while the site was blocked. "I'm guessing that the experience has not left you permanently banned from any search engines. True/False?)

What I'm referring to are IPs that are banned mainly for trying to psych out the search engines by attempting to get a higher search engine ranking using methods that are banned by search engines (i.e. creating key words that are the same color as the background).

The question rephrased is: "Does a site that is banned because they used techniques to get a better search engine ranking mean that all the other sites sharing the same IP also are banned?"

I'm trying to find if anyone actually has had this experience--not one of those, "I heard someone say..." And if so how recent was the experience?

I don't think it works that way.

Site X, let's call it, on Server A, sends mail to newbie@isp.com. User "newbie", for whatever reason, reports the message to his ISP as being spam (reported possibly fraudulently, but that's another issue/rant for another time).

This ISP, sadly, subscribes to Spam-Killers-R-Us, a brute-force directory of IP addresses from which spam has been reported (but not proved) to have been sent. The IP address of Server A is added to the list.

Any ISP that uses the crude (and discredited) filtering method of barring all messages from any IP on the Spam-Killers-R-Us list will now ban all messages sent through the mail server on Server A.

You also have a site hosted on Server A. You can still send mail, and users can still access your site.

Suppose user "newbie" visits your site. His ISP does not block access to your site; "newbie" can move around your pages at will. Suppose "newbie" uses your contact form to send you a message. You get his message. You try to reply. But "newbie" can't receive your reply, because his ISP won't accept mail from Server A.

You get around this by replying to "newbie" through another mail server, perhaps your own ISPs, apologizing for and explaining the delay in your reply, and mentioning that it might be nice if his ISP wasn't so backward.

This (temporary) banning by some ISPs of mail from your server is not the same as the banning of bots (through robots.txt, for instance) by your server. They're two different issues -- fortunately!

No, the fact that my sister (and a few other people with ISPs that use these outdated methods) couldn't get mail from me for a bit had absolutely no effect on my search-engine ranking. It was mostly just an annoyance for me and my sis.

Sites are banned from the search engines by domain name, just as sites are listed in the search engines by domain name. If the rankings were by IP address, then all you'd need for a good page-rank would be to reside on the same server as a well-ranked site, and that clearly isn't so.

Now, if you host forty-twelve different sites -- all link-farms and/or affiliate ad-riddled sites, cross-linked to an implausible degree -- on the same server, then the search engines might notice that "something is afoot". But that's about the only way (that I can think of) that IP might enter into things.

If you're asking "Will I be banned from Google just because some moron on the same server did something really stupid?", the answer is "no". As long as you aren't connected to the moron (by links, for instance), then you shouldn't experience any of his problems.

Hope that helps!

That info is insightful and appreciated.

So..., I'm guessing that you agree that web sites being banned because of a shared IP is an Urban Myth.

I'd never even heard of this "myth" before you'd posted it.
