		<description><![CDATA[The Christmas Goat attracted 809 unique AS numbers this year, with IPv6 usage led by the USA and Finland. Despite a rise to 39% IPv6 adoption, challenges like outdated routers persist. As this 15-year tradition concludes, the holiday Goat highlights the progress and hurdles of IPv6 integration. <a href="https://circleid.com/poststhe-christmas-goat-and-ipv6-year-15">More...</a>]]></description>

		<title> Do We Need IPv4 at Home/SOHO Any More? (Featured Blog)</title>

		<description><![CDATA[CLAT/NAT64 is utilized across many mobile networks globally, and I am only talking about Ethernet and Wi-Fi in home and small office/home office (SOHO) environments. I experimented by completely disabling IPv4 at home and established a SSID where my MacBook Pro operates without an actual IPv4 address. The MacBook supports CLAT (RFC 6877), and by implementing PREF64 (RFC 8781) and DHCP Option 108 (RFC 8925) in my network, I was able to achieve a 100% IPv6 environment. <a href="https://circleid.com/posts20240502-do-we-need-ipv4-at-home-soho-any-more">More...</a>]]></description>

		<description><![CDATA[A new year and a new goat with new conditions, the goat was slowly eaten by jackdaws, and in the end, almost only the frame remained. This was really slow TV for the devastation… You can read more on Wikipedia about the devastating jackdaws and the straw... 36% IPv6 is equal to last year, and I had high hopes as Telia (AS3301) has made great progress in IPv6 and that Sweden should be the dominant country.  <a href="https://circleid.com/posts20240108-the-christmas-goat-and-ipv6-year-14">More...</a>]]></description>

		<description><![CDATA[2022 was not a normal year for me. We sold our company of almost 25 years to Interlan Gefle AB to Nordlo Group, and I also moved away from Gävle city to Boänge, a small rural village outside Sandviken where my ISP (AS20626) still isn't ready for IPv6 in my location.... ☹ ( I use a Mikrotik with a Wireguard tunnel to solve my IPv6 today.) It's 2023 when I'm writing this, and I can't understand why ISPs still haven't deployed IPv6! <a href="https://circleid.com/posts20230102-the-christmas-goat-and-ipv6-year-13">More...</a>]]></description>

		<description><![CDATA[This year could be the fifth year in a row where the goat isn't burned down. But early in the morning of Dec 17th, it was on fire by an arsonist who got caught a few minutes later. So Stephan Lagerholm, who had visited me earlier for some IPv6 site seeing in Gävle and I were lucky to get this photo. The traffic went down by 5% from last year, and I don't have any good explanation for that. The visitors with many hits in the logs are always from the same countries where North America and Europe are dominating. <a href="https://circleid.com/posts20211220-the-christmas-goat-and-ipv6-year-12">More...</a>]]></description>

		<description><![CDATA[This is the fourth year now with almost no snow during <a href="https://en.wikipedia.org/wiki/G%C3%A4vle_goat">the Christmas Goat</a> event here in Sweden, and so once again, you get a photo without any snow. Because of Covid-19 and 99.99% people working for home, I have not even seen the Goat live this year... What a crazy year it has been! <a href="https://circleid.com/posts20201230-the-christmas-goat-and-ipv6-year-11">More...</a>]]></description>

		<description><![CDATA[This year marked the 10th anniversary of collecting statistics for IPv6 from the Christmas Goat. It's the third year now with almost no snow, and with this crazy winters and climate, it's hard to get any good photos of the goat. The photo is only from 3&ndash;4 days in early December with little snow so far in Gävle.The measurements this year started very low with 20% IPv6, but it made some improvements and landed just like 2018 at a total of 41%. <a href="https://circleid.com/posts20200104_the_christmas_goat_and_ipv6_year_10">More...</a>]]></description>

		<description><![CDATA[Here we are with the ninth year of measuring IPv6 on the Christmas Goat. Last year we had almost no snow and it's almost the same this year. This year I give you 50 seconds of "action" film with the goat from the early in December. But the measurement was a big disappointment. They started high with 60% IPv6 and went down to 41% at the end. But as can be seen with the progress, next year we should easily break the 50% barrier! <a href="https://circleid.com/posts20190102_the_christmas_goat_and_ipv6_year_9">More...</a>]]></description>

		<description><![CDATA[This is the eighth year we measure IPv6 on the Christmas Goat. And with the crazy climate we have to live in now where there is no snow on the goat or ground. But IPv6 is doing better than the climate this year. This year we increased from 27% 2016 to 40% 2017. In Sweden Tele2, Tre and Comhem are still the only major ISPs with IPv6 enabled. Tele2 (with IPv6 since ~three years) and Tre is mostly mobile operators, and Comhem has enabled IPv6 in their Docsis network. <a href="https://circleid.com/posts20171227_the_christmas_goat_and_ipv6_year_8">More...</a>]]></description>

		<description><![CDATA[It was a great year for the goat! 2016 marked the 50th anniversary for the Christmas Goat and there was a grand opening ceremony along with music and fireworks. But only a few hours after the opening, a pyromaniac set the goat on fire. The only track the police have is a cap above that they hope to find DNA in and a crappy picture of the pyromaniac's back. <a href="https://circleid.com/posts20161214_the_christmas_goat_and_ipv6_year_7">More...</a>]]></description>

		<description><![CDATA[When I last year failed to take a picture of the Christmas goat before it was taken down, I decided this year to take a pic every minute, just to be on the safe side. A shortened movie based on these pics of the 2015 Christmas Goat can be find on YouTube. The clip on YouTube also shows that in the early morning of December the 27th the goat was set on fire and burned down in minutes. <a href="https://circleid.com/posts20151229_the_christmas_goat_and_ipv6_year_6">More...</a>]]></description>

		<description><![CDATA[This year I didn't even get a good picture of our famous Christmas goat here in the city of Gavle Sweden. The Christmas goat this year survived Christmas but were suddenly on the 28th of December dismounted. The reason for the poor goat's early leave from its own little park downtown Gavle is that it is now the year of the goat in China, and the city of Gavle has a sister-town in China -- Zhuhai. <a href="https://circleid.com/posts20150108_the_christmas_goat_and_ipv6_year_5">More...</a>]]></description>

		<description><![CDATA[This year, 2013, I got 24 days of IPv6 and DNSSEC measurements. All in all it created 15GB logs with more than 62 million rows. On the 21st of December, early in the morning, the goat was "traditionally" burnt down, however this year with one exception. Via the Swedish newspaper Expressen the arsonists anonymously took the blame and also filmed their own act. <a href="https://circleid.com/posts20140102_the_christmas_goat_is_on_fire_fourth_season">More...</a>]]></description>

		<description><![CDATA[As Christmas were getting closer, the third time of load balancing the streaming pictures of the famous Christmas goat in the city of Gävle, Sweden, was on the agenda. My goal with this activity is the same as before, to track the use of IPv6 and DNSSEC validation. The results from the last two years are published on CircleID. <a href="https://circleid.com/posts20121220_the_christmas_goat_ipv6_and_dnssec_third_season">More...</a>]]></description>

		<description><![CDATA[A very long time ago, back in the ancient time of year 2006, the registry for .se domains, also called .SE, opened up for signing .se zones with DNSSEC. In those days .SE did not have a registrar/registry model and my own company Interlan was then an agent for .SE. One day I suddenly got a mail from .SE regarding secure DNS -- DNSSEC. ...I almost immediately saw the benefits that such a solution could give to a better and more secure Internet. <a href="https://circleid.com/posts20120823_the_mailbox_that_saved_dnssec">More...</a>]]></description>
