Ping() returns negative number

Hi,

I can't seem to reproduce this, but once in a while, the Ping() function returns a negative number.
My internet connection is stable and doesn't disconnect, no other apps report a lack at connectivity.

ConsoleWrite(TCPNameToIP("www.google.com"))
ConsoleWrite(Ping("www.google.com"))

I'm not sure if it's an issue with my provider's DNS that causes it to return a negative number or not. But the name does resolve to an IP address properly.

Has anyone else seen this? Is there a fix?
