How do routers differ from ISPs?
An ISP (internet service provider) is a large organisation providing internet services to your site's visitors. A router is a device that an ISP uses to provide access to the internet. ISPs may own numerous routers. Every visitor is directed through a router, but not all routers provide their identity.
Reverse dns lookup: Reverse DNS turns an IP address into a hostname. The process involves identifying a host name that corresponds to an IP address using the Domain Name System. To do this, IP addresses are entered into a DNS database and thus resolved to domains, if possible.
