When we talk about IP addresses of home computers, we are usually referring to two types of address. That’s the one that the world sees, and every internet connection, website, or public-facing web-connected thing will have one. ”, it’ll tell you what your public IP address is, as given to you by your ISP (note, if you’re using a VPN, this will come from your VPN provider instead).
Then you have internal, private IPs, which are only used on your home network.
(Internet Protocol address) The address of a connected device in an IP network (TCP/IP network), which is the worldwide standard both inhouse and on the Internet.
Every desktop and laptop computer, server, scanner, printer, modem, router, smartphone, tablet and smart TV is assigned an IP address, and every IP packet traversing an IP network contains a source IP address and a destination IP address.
In the following example, we’ve added a DHCP Reservation for the device with the MAC address E0: CB:4E: A5:7C:9D, currently with IP 192.168.0.10.
You can also change the IP address to something new if you like, but you will need to restart the device in order to get the new address. You can keep your special routing rules the same, and if a device or server restarts, it’ll simply be given the same IP next time.
It’s the job of your router to assign a new IP address when a device joins the network and maintain a phone book of who has what number.
A static IP address (also known as fixed IP address) is simply one that doesn’t change.
