Modern routers include a system called Universal Plug’n’Play Technology in the computer age has been plagued with unsecured features, security loopholes, and general oversights in software architecture. For example, if you set one of your machines to the IP address 192.168.0.10, and your router continues to hand out IP addresses automatically, then at some point, another machine will be given the same IP! By doing this, we ensure our machines have an IP address that will never change, without actually assigning a static IP address, which would complicate things.
Instructions on how to do this will vary depending on your router manufacturer and model.
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.
They look exactly the same: four numbers up to 255, with a period in between.
There are a few possible ranges of private IP address, but for most home users this will be 192.168.*.* or 10.0.*.* (where * can be anything).
(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.
If your server was to restart, it would get a new IP from the router.
The port forwarding rule you created to send requests on port 80 to the old server IP address wouldn’t work anymore. You will need to make a few changes to your router configuration.
