The Internet Protocol (IP) system designates how networked devices can address one another across the internet. The first major version of IP, IPv4, was deployed to the public ARPANET in 1983. IPv4 uses 4 one byte segments to designate a devices address, this 32-bit address space allows for 232 addresses to be used in total. The next major iteration of IP is called IPv6 and it uses a 128-bit address space allowing for significantly more IP addresses to be assigned. Continue reading “Difference Between ipv4 and ipv6”
localhost is a networking term; it’s the hostname for the loopback network interface of whichever server it’s said in reference to (meaning every server has a ‘localhost‘). The loopback interface bypasses any local network interface hardware, and serves as a method to connect back to the server itself. The term localhost is used often in both networking and in server administration.
The IPv4 address for localhost, or the loopback network interface, is 127.0.0.1.
The IPv6 address for localhost, or the loopback network interface, is ::1.
