So what's the difference between static and dynamic IP addresses? Static IPs are usually used by companies. Their IP address is often (not always) listed in the public directory and usually doesn't change. This makes it very easy to track when someone from that company visits your website. Dynamic IPs are given (typically) to home users or small businesses. These dynamic IPs usually stay with one device for weeks to several months and change once the user resets or unplugs their router.
When people work from home, they switch from a Static IP address to a Dynamic one. That could be very bad. But it's not. Luckily, we track both dynamic and static IPs — and then match them with a custom database. As macedonia email list you can imagine, the static IP address database is easier to build than the dynamic one — simply because static IP addresses don't generally change, and public data is available.
Once we know the IP address for Microsoft's Washington state office, we know anyone with that address works for Microsoft. Both Static and Dynamic IP addresses use the same sources. However, the dynamic database is very dependent on the data we receive from additional data sources. So, how do we know John Doe works for Microsoft when he's working from home a dozen or more miles from the office? We use multiple commercially available databases, plus our engineering team has developed algorithms to combine the commercially available databases with our own proprietary database effectively.
