As long as your URL stays the same, your site's listing in Google shouldn't be affected if you switch hosting companies or change your IP address. We recommend migrating a site to a new IP address with the following steps: 1. Bring a copy of your site up at the new IP address. 2. Update your nameserver to point to the new IP address. 3. Once you see search engine spiders fetch pages from the new IP address (typically within 24-48 hours), it's safe to take down the copy of your site at the old IP address
