Converts an IP address string to an IPAddress instance.
Assembly: System (in System.dll)
The static method creates an IPAddress instance from an IP address expressed in dotted-quad notation for IPv4 and in colon-hexadecimal notation for IPv6.
The number of parts (each part is separated by a period) in ipString determines how the IP address is constructed. A one part address is stored directly in the network address. A two part address, convenient for specifying a class A address, puts the leading part in the first byte and the trailing part in the right-most three bytes of the network address. A three part address, convenient for specifying a class B address, puts the first part in the first byte, the second part in the second byte, and the final part in the right-most two bytes of the network address. For example:
Number of parts and example ipString
IPv4 address for IPAddress
1 -- "65536"
2 -- "20.2"
2 -- "20.65535"
3 -- "128.1.2"
