I was looking into changing my IP as I have dynamic IP, but I'm connected through a router. So from my research I came to understand that the router has it's own IP that identifies it on the net, and then it assigns different IPs to computers connected through it, but the computers on the internet identify through the router IP, not their individual ones.
So I go into my router settings, and go to WAN Setup and click Assign WAN IP manually. I tried making a completely different router IP, but when I click save changes, it won't let me because it says invalid Subnet Mask. Then I tried changing the last numbers of IP (example: xx.xxx.xxx.123-> .124), but then my internet stops working completely.
Any ideas on how to change my IP without completely having it shit the bed?
