Implementing PING through MFC coding.I want to implement to find whether a given URL is a valid one or not

[Orlando]

Hi,

Technically I don't think thet PING proves conclusively that a given host name is valid because PING will fail if the remote computer is down or unreachable for some reason.


Like all TCP/Ip utilities first the IP subsystem has to get the IP address

of a given URL (probably via the Gethostbyname function).


The GetHostByName function may be a better way. At least it would show if the URL exist in any of the Internet DNS databases.


Maybe someone could verify/correct me on this point
