.NET Forum / Languages / Managed C++ / March 2005Validating IP & MAC Addresses ...
Hi, - Is there a function that can validate IP addresses? - Is there a function that can validate MAC addresses? Hugo 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. - MR > Hi, > > - Is there a function that can validate IP addresses? > - Is there a function that can validate MAC addresses? > > Hugo 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. -- With Regards Alok Gupta Visit me at http://alok.bizhat.com "I Believe this will Help" > Hi, > > - Is there a function that can validate IP addresses? > - Is there a function that can validate MAC addresses? > > Hugo It depends on your definition of valid MAC address and valid IP address. > Hi, > > - Is there a function that can validate IP addresses? > - Is there a function that can validate MAC addresses? > > Hugo 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.
