Do the Dart products (Winsock, SNMP Agent, Server, Web Server) run on top of an IPv6 network? My understanding is that as long as the OS supports IPv6 then it should be no probloem but it would be nice to see a compliance statement from Dart in this respect.

Hello Brendan,

I am not sure as I have never tried, but I do not see any reason why they should not be working on it.
You may try it and let us know incase you face any issues.

Have a great day.

Regards,

According to MS there is some work that will be needed (see below). The support of IPv6 - is this something Dart will do at their own cost?

Q. How does my existing Windows Sockets for IPv4 code need to be modified to support IPv6?
 
A. The Windows Platform SDK includes a tool called Checkv4.exe. Checkv4.exe scans source code files to identify code that needs to be changed to support IPv6. Checkv4 displays the line number and a message recommending how the code should be changed. Here is an example of Checkv4.exe output:

test.c(35) : gethostbyname : use getaddrinfo instead

test.c(40) : gethostbyaddr : use getnameinfo instead

test.c(48) : SOCKADDR_IN : use SOCKADDR_STORAGE instead, or use

SOCKADDR_IN6 in addition for IPv6 support

test.c(57) : AF_INET : use AF_INET6 in addition for IPv6 support

test.c(89) : inet_addr : use WSAStringToAddress or getaddrinfo with

AI_NUMERICHOST instead

For more information, see Using the Checkv4.exe Utility.

For detailed information about modifying your applications to work over both IPv4 and IPv6, see the IPv6 Guide for Windows Sockets Applications.

We do plan to add support for IPV6 but currently don't have a time line set for release.

Thanks for the information. If we asked for it to be deliverd by Nov 2008 do you think that would be possible, and if not then what would it take to make it available by that date?
