There are two types of IP addresses: Public IP and Private IP
Private IPs are added on the LAN network Public IPs are added on the WAN network…. IPs are IPv4 and IPv6
IP VERSION 4 (IPv4) is an IP with 4 octets (for example, 192.168.1.10) used in dotted decimal format between octets.
192 = first Octet
168 = Second Octet
1 = Third Octet
10 = Fourth Octet
Of the four octets, the first octet can be used to determine whether it is a public IP or a private IP.
