The Elliptic Curve Cryptography (ECC) is becoming increasingly popular in DNSSEC. While it is sometimes considered to be a remedy for the low DNSSEC adoption rate, there is also a lot of controversy around it. One of the main concerns is that DNSSEC-validating resolvers don't always make use of ECC…

This week, the RIPE NCC saw a milestone as the 10,000th Local Internet Registry (LIR) received IPv6 addresses. The first block of IPv6 addresses was allocated from IANA to the RIPE NCC in 1999, so we have been distributing IPv6 addresses for 17 years. In those years we have seen interesting poli…

We tend to make a number of assumptions about the Internet, and sometimes these assumptions don’t always stand up to critical analysis. We were perhaps ‘trained’ by the claims of the telephone service to believe that these communications networks supported a model of universal connectivity. Any tel…
