My internet IP is 86.xxx.xxx.xxx. My router had DCHP switched on. and router is 192.168.1.254. Now all appliances ahould be on 196.168.1.xxx. now my problem is that most of my devices change the ip to 86.xxx.xxx.xxx,the olny way that i can stop this happening is to apply a static IP manually through iphone settings. can anyone explain why this is happening?
