URL: Uniform Resource LocatorĪ live website is hosted/stored on a webserver and consists of different files such as HTML pages, png graphics, jpg pictures, gif animations and other multimedia files (mp3 audio clips, mp4 movie clips, pdf documents etc.). Networking equipment such as routers and switches use IP addresses and/or MAC addresses to direct traffic between computers/devices on the network. (A bit like the chassis number of a car!) It is hardcoded into the device by the manufacturer when the device is built. They are expressed in hexadecimal using 8 blocks of 2 Bytes (4 hexadecimal digits) separated by colons e.g.:Ī MAC Address is static and unique for a device. IPv6 addresses consist of 16 Bytes (=128 bits). To overcome the issue of the Internet running out of unique IPv4 addresses, a new format was introduced. This is the reason why the Internet is progressively upgrading to the next generation of IP addresses: IPv6… IPv6 Addresses Remember, every device (router, computer, smartphone, smartwatch, smart TV, smart speaker, etc.) connected to the Internet will have its own IP address and there are nearly 8 billions human beings on planet Earth. Though this seems like a large number, we are reaching a stage where we are running out of unique IP addresses. Some devices can be configured on an IP network to have a static IP address: it will remain she same even if you restart your device.Īs an IPv4 address consists of 4 Bytes (=32 bits), there are 2 32 possible IP addresses which is just under 4.3 billions IP addresses. A dynamic IP Address can change every time your restart your device/reconnect to the network.
