We have released support for searches which can have multiple search results as a follow-up to our RIPE Labs publication of a direct lookup API and form.
Measurements and Statistics
Pollution in 1/8 - A Follow up
• 3 min read
Following up from measurements done in February 2009 just after 1/8 had been allocated to APNIC, we looked at the data again and made some additional observations.

The roll-out of a signed root-zone at K-root on 24 March 2010 was uneventful. But we saw the number of resolvers doing priming queries increase slightly since 18 March 2010 and wanted to find out why.
Spam over IPv6

With the increased deployment of IPv6, we were curious to see how much the amount of spam sent over IPv6 increases.

In Part 1 of this article we showed some statistics on IPv6 at end-users and at caching DNS resolvers. In this part will dig deeper into the data we collected and show details on mobile device use of IPv6, country- and city-level IPv6 deployment numbers, and AS-level statistics.

It is important to keep an eye on how the IPv6 Internet develops. We wrote a script to measure the IPv4 capability, IPv6 capability and IPv4/IPv6 preference of end-users visiting our site. What is unique about this script is that it allows us also to measure the caching DNS resolver that the end-us…
Find Abuse Handler Details Using the Abuse Finder
• 4 min read
The RIPE Database contains a lot of useful information about who to contact in case of network abuse or spam. But sometimes it can be difficult to find the right abuse handler information for a network resource in the RIPE Database. We developed an Abuse Finder tool that will make it easier.

In this article we take a look at DNS priming queries arriving during the deployment of a DNSSEC signed zone at the DNS root servers. We are specifically looking for potential problems as a result of this deployment.

On 30 January 2010 the RIR system reached a small milestone: on this day APNIC has surpassed the RIPE NCC in terms of total allocated/assigned IPv4 address space, as seen in the RIR stats files. On this occasion we decided to look a bit into how IPv4 allocation/assignment rates changed over the las…
