Validating IP & MAC Addresses ...

[H.B.]

Hi,

- Is there a function that can validate IP addresses?
- Is there a function that can validate MAC addresses?

Maybe, and No...

However:

A MAC is simply a char[6] (6 bytes, not actually a string) and any 6 bytes
are valid - but some manufacturers / card ID's wont have been assigned. No
way to tell...

IP Wise look up illegal addresses and such.

I believe you have to write your own Api to validate correct IP adress and
Mac Address as Microsoft Doesn't rpovide any api yet to check that.

It depends on your definition of valid MAC address and valid IP address.

It's about syntax ...

I must validate syntax for two strings : IP string (xxx.xxx.xxx.xxx) and
MAC string. (xx-xx-xx-xx-xx-xx)

That should be easy enough, the IP segments are between 0-255 and MAC
segments should be in the range (hex) 00-FF.
