What is ARP Cache?
ARP, which stands for Address Resolution Protocol, is like a digital phone book for devices on your Wi-Fi. It helps your gadgets talk to each other. The ARP Cache is like a memory bank in your computer, storing these phone numbers. Sometimes, this memory can get mixed up, causing internet problems.
Here’s the thing: only devices on your Wi-Fi can change this memory. Imagine ARP messages as public announcements in your neighborhood. Devices that can hear these announcements update their memory accordingly. So, someone on your Wi-Fi, intentionally or even unknowingly, can mess with this memory.
Changing the ARP Cache is serious business. Usually, it needs fixing when someone tries to force a change that the system doesn’t support, making things worse. So, it’s best to avoid messing with it unless you really know what you’re doing
