Explanation:

The Internet is based on a U.S. government project called Advanced Research Projects Agency (ARPA). Today, the Internet is a collection of networks, tied together by common protocols. Tier 1 networks form the Internet infrastructure, a system of high-capacity routers and fiber-optic communication links arranged in a mesh topology. Networks that form the Internet are maintained by internet service providers (ISPs) that offer access to consumers. Before data travels over the Internet, it is divided into packets by a protocol called transmission control protocol (TCP), which also reassembles the data when it reaches its destination. Every device on the Internet uses an IP address. IPv4 addresses are 32 bits long, whereas IPv6 addresses are 128 bits long, providing billions and billions of possible addresses. Addresses are assigned by DHCP servers.

IP addresses that are temporarily assigned are called dynamic addresses, whereas permanent ones are called static addresses. Private IP addresses cannot be routed over the Internet and are usually assigned to devices within LANs. Because it is difficult to remember IP addresses domain, the name system allocates easy-to-remember domain names. Top level domains include .com and .edu. The servers that track these names are a vulnerable point in Internet security.
