My router WAN IP is 10.0.51.132 and subnet mask of 255.255.255.255 and my external IP is something static that is always the same when I write "what is my IP" in google. The WAN IP which is 10.0.51.132 it keeps changing.
So I assume my ISP has a DHCP server that gives us some dynamic IP and we are connected via PPPOE (username/password) but how is the subnet mask 255.255.255.255.
Can I connect with someone in LAN within my ISP?

Q# 1 - Now can PC connected to my router which has a subnet mask of 255.255.255.255 connect to PC3 connected to router1 which is another home taking internet from the same ISP with random IP and subnet mask of 255.255.255.255 connect?
Q# 2 - Can I also set the same thing in my router DHCP to give subnet mask of 255.255.255.255 to all the devices connected so they can not communicate in LAN but directly to the router?
Q# 3 - Will giving that subnet mask affect the performance of the network?
Q# 4 - Is the static IP that shows in "What is my IP" also possibly the Static IP of other connections that ISP has given?
Q# 5 - Am I double NATTED? if yes how much does it put the latency in a local connection?
