How to listen on a socket in the modern IPv6-enabled world
Suppose that you are a fancy modern server program, and you want tolisten for both IPv4 and (if available) IPv6 connections. As it happensthis is a bit more intricate than you might expect, and it variesbetween systems.
To start with:
- use
getaddrinfo()with a NULL host, the port you want,AF_UNSPECas the address family, andAI_PASSIVEandAI_ADDRCONFIGin the flags. - if the results don't contain any IPv6 sockets, you have

What Linux's getaddrinfo() is doing with IPv6 (on some versions)
I've previously noted that Linux's getaddrinfo() implementationdoesn't return IPv6 addresses by default if it doesn't think that yoursystem is IPv6 capable, or perhaps if your system has IPv6 disabled(this is most conveniently visible through the Python interface ). This behavior is more or less the same aswhat you'd get if you supplied the AI_ADDRCONFIG flag in the hints structure.
(To be specific, I have seen this behavior on Ubuntu 8.04

Archdiocese of Saint Louis Redesigns Website
The Archdiocese of Saint Louis today upgraded its entire website to a new design and a new platform, allowing offices and agencies to more quickly and more easily communicate with the faithful in the Archdiocese (and around the world!).
I've been working on this project (with a lot of help from Palantir, a web development company in Chicago) and some local developers for the past year, and I am pleased with the result (I hope you are, too!). I've written up more
