Any website that is connected to the Internet receives an identifying label called an Internet Protocol address, which is a critical component in the process that allows one device such as a web browser program to access information stored on another device such as a server. Whenever a browser is used to open up a website, the computer running the browser essentially shares the IP address representing its particular location on the Internet with the server hosting the website so that the server knows where to send its response data. An IP address often appears as a set of numbers with decimal points placed at three positions throughout the address. IP addresses are not always exclusive to one individual device each, however. Online hosting companies often provide services where many websites are hosted on what is more-or-less the same IP address. Even if these websites are not thematically related otherwise, they will cause external services such as Google Analytics and Google Search Console to assume that they should be counted as part of one distinct "identity" with one IP address hosting it. This will always compromise at least some of the sites hosted on that address in some way. For example, the owner of one of those websites might want to use the aforementioned Google services to gauge its SEO quality, but the data will be contaminated because it would essentially be an amalgam of the data for all of the sites on the hosting address. Any website that is trying to function as a viable extension of its company's business will be especially harmed by this unneeded association with an entire collection of unrelated sites because any substandard SEO present on those sites will undermine the quality SEO that the website is relying on. This is why owning a website with its own IP address is widely regarded as one of the most basic steps a business can take when establishing its presence online with a new website. It is also a simple process for a website hosted on a shared IP to migrate to a more distinct one. For more information click here https://www.reddit.com/r/SEO/comments/9eg6im/seoandshared_vps/.
