Determines whether a string is a valid IP address.
Assembly: System.Net (in System.Net.dll)
This method tries to parse an IP address expressed in dotted-quad notation for IPv4 or an IP address expressed in colon-hexadecimal notation for IPv6.
For IPv4, 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"
For IPv6, the Scope Id is also parsed and validated if this present in the ipString parameter.
