IP address change and SEO

We are migrating our server to a new Data Center. Usually changes of IP address shouldn't be a problem in regards ro SEO.

However,

1. In some rare cases IP address were used in bad neighborhoods. Do you guys know how to check the history of an IP address?

2. Would you try to migrate also the old IP address and keep it and after a day or two even make it your primary IP again (in the DNS)?

Thanks!

I have no idea about SEO implication of an IP, but I know it can have a serious impact, if your server is sending mails, because the IP can be blacklisted, if used by spammers "before". To check , I use this site : [blacklistalert.org...]

I am not sure I understood the second question. But even if your new DNS is propagated, you should expect some requests continuing to reach your "old" IP for some times.So I would keep the old IP for one week or a whole month to be sure.

The IP we are going to use was flagged in apews.org.

All others were OK.
The checklist on Symantec gave also Ok.

Would you change it? Is there a way to find a 100% clean IP?

Don't worry about it. It's been nearly a decade since Google last took an action on an IP address, and for good reason. It's a very different environment now. Bad sites are rarely so clustered and isolated that Google could penalize a range of IP addresses without significant collateral damage to innocent sites.

The IP you are migrating to is no longer "tainted", else it would not be available. rainborick has it right ... at least that is the way it has worked for me over the last few years.

I never noticed any negative impact in the last decade, so my experience reflects that of others. I have however had serious email deliverability issues in the past by moving into a bad neighbourhood unwittingly. This caveat cannot be understated.

@Xpat How did find out to be in a bad neighborhood? Did you check against blacklisted IPs?

My emails were sent to a black hole by just about any mail server on the planet. My host was allowing spammers to enjoy cheap VPS accounts and their entire IP space was blacklisted at services such as projecthoneypot. I only noticed when I went days without a reply to any of my emails.
