Hi,
Can someone provide a complete set of rules for the IPAddress.Parse
function? The remarks section in the .NET Framework Class Library provides
some of the rules but it appears that .010 for example is interpreted in
Octal. Does this mean that one can mix octal, decimal and hexadecimal octets?

What are the other rules?

In .NET 2.0 IPAddres.Parse and TryParse just delegate to the WinSock function
inet_addr for IPv4 addresses. The documentation for inet_addr details what
constitutes a valid IPv4 address:
