Validating ip address c

Currently I have the following code to validate the first format. Also, please suggest a mechanism tovalidate the second format(address:port) also.#define INVALID -1#define VALID 0int validate IP(char *ipadd) This looks exactly like code I've posted a couple of years ago.

The more paranoid check at the end was added in response to some criticism from Tak-Shing :-) Extending it for IPAddressv4:port shouldn't be that difficult to anyone who has understood how the current version works (which, of course, excludes qazmlp).

Trivia quiz: what is the purpose of the last check? 78" would pass all the other tests, yet it hardly looks like a valid IP address.

I find myself many times writing an Advanced Function that takes as its parameters only IP Addresses. Error: "An invalid IP address was specified."

A quick way I found for validating that an IP Address was passed is using the [IPAddress] Type Accelerator and the parameter option of [Validate Script()] if we look at the type accelerator it self if we pass a valid IPv4 or IPv6 Address we get an IPAddress object: [ipaddress]"192.168.1.1" Address : 16885952 Address Family : Inter Network Scope Id : Is IPv6Multicast : False Is IPv6Link Local : False Is IPv6Site Local : False Is IPv6Teredo : False Is IPv4Mapped To IPv6 : False IPAddress To String : 192.168.1.1 [ipaddress]"260.0.0.1" Cannot convert value "260.0.0.1" to type "System.
