		<description><![CDATA[I&#8217;ve started a separate blog to inspire people to learn more about IPv6 and start their own labs. It&#8217;s called IPv6friday.org and publishes a short article about IPv6 every Friday. I don&#8217;t know how the idea got started &#8211; I think it was just this Tweet that got a lot of responses. The main problem [...]]]></description>

		<description><![CDATA[RFC 3261, The Session Initiation Protocol, was published in 2002, six years after the initial work on SIP. Wikipedia writes &#8220;SIP was originally designed by Henning Schulzrinne and Mark Handley in 1996. In November 2000, SIP was accepted as a 3GPP signaling protocol and permanent element of the IP Multimedia Subsystem (IMS) architecture for IP-based streaming multimedia services in cellular systems. The latest version [...]]]></description>

		<description><![CDATA[A modern SIP invite with SIP identity, outbound, ice and hopefully S/MIME will cause UDP fragmentation. A SIP stack that wants to stay up to date supports TCP. Anyone implementing a SIP network wants to support TCP. When we are there, beyond UDP, we might as well think about using TLS. Is it time to [...]]]></description>

		<description><![CDATA[Lately, I&#8217;ve been going through a lot of SIP RFCs and drafts, trying to get an overview of the security suggested in all of these documents. The quality of this work, seen from a developer&#8217;s perspective, is quite poor. Sometimes it seems like authors think, &#8220;oh, we need to add that security stuff, so let&#8217;s [...]]]></description>

		<description><![CDATA[Yesterday I found an Internet Draft called Testing Eyeball Happiness that gives examples on how to test dual stack deployments. There is a known issue with applications that retrieves multiple IP addresses from the same host name in DNS and , following current RFCs, test them sequentially with a preference for IPv6 addresses. The timeouts when things [...]]]></description>
