has-ipv6
Returns a value indicating whether one of specified IPv6 addresses appears in a text.
IP-prefix notation is a concise way of representing an IP address and its associated network mask. The format is /, where the prefix length is the number of leading 1 bits in the netmask. The prefix length determines the range of IP addresses that belong to the network.
For IPv6, the prefix length is a number between 0 and 128. So the notation fe80::85d:e82c:9446:7994/120 represents the IP address fe80::85d:e82c:9446:7994 with a netmask of ffff:ffff:ffff:ffff:ffff:ffff:ffff:ff00. This netmask has 120 leading 1 bits, or a prefix length of 120.
