I kinda get how it makes sense on a local network, because it’s kinda like a list of the devices that are connected to it and your trying to communicate with other machines connected together in that same list. But this feels like a really surface level understanding and I don’t know what I’m missing.
I understand that they’re a string of 4 digits from 1-255, such as 192.168.1.1 being really common for home networks. But I don’t know what the numbers each mean. I think 192 in this case is a reserved value for home use? Same with 10? And the last number is basically the number of the device on the network I think. But I don’t understand the numbers for x.168.1.x
What I really don’t understand is how public IPs work. You hear online about not leaking or sharing your public IP or it can be used to find (pretty close to) where you live. How? How are they assigned to the billions of connected devices in the world?
I’ve been watching videos about trying to set up a FOSS router because it’s really interesting, but IPs seem like dark magic to me
In: Technology
Local IP addresses like 192.168.1.1 are used within your home network to identify devices. They help your devices communicate with each other and aren’t visible on the internet. 192.168.x.x and 10.x.x.x are common ranges for these private addresses.
Public IP addresses allow other networks to send data to you. Your ISP assigns you a public IP when you go online. Public IPs can reveal your general location because ISPs distribute them based on regions.
