+For the St Nicholas' Day we present you with something that has been
+requested from the communtiy: [A new IPv6 ULA
+registry is born](https://ula.ungleich.ch).
 
 
+## Background
+
+The [original IPv6 ULA
+registry](https://www.sixxs.net/tools/grh/ula/list/) was maintained by
+SixXS. However with the sunset event of SixXS on 2017-06-06, the
+database has essentially become static.
+
+At this point we want to say many, many thanks to the SixXS project to
+provide so much pioneer work and to prepare the way for people to
+embrace IPv6.
+
+Also for providing such an early and machine readable database - it
+was a pleasure importing all the historic records.
