IP address format is 4 Octets
which is four sets of 8 bits like in the above mentionted Table
255.255.255.255.255 is four sets of 11111111
Every IP address range you have to subtract 2 because the First is the network address and the Last is the Broadcast address
But you will always assign another to your Gateway which is usually the first number after the network address
Public IP Vs Private IP
Public IPs are the address of your router to the rest of the world
Private IPs are the IPs that you use in your network
NAT - Network address Translation takes your private ip at your router and turns it into your routers IP to surf the internet outside of your network
The process of dividing a larger network into smaller more managable networks called subnets
A subnet is like a smaller group within a large network
A Subnet mask is a 32-bit number (Same as an IPv4) used in IP addressing to seperate the network portion of an IP address from the Host portion shows network ID and Host ID
An IP address of 192.168.1.42 with a subnet mask of 255.255.255.0
the first 3 octets are the Network ID and the Last Octet is the Host ID
to test connectivity

Simplify IPV6 if there is 0000:0000 you can simplify it with ::
loop back address in IPv6
