IPv6-Day DITL Data Collection

A Day in the Life of the Internet is a large-scale data collection project undertaken by CAIDA and OARC every year since 2006. In addition to the recently completed 2011 collection, DNS-OARC is sponsoring a IPv6-Day collection. If you would like to participate by collecting and contributing DNS packet captures, please subscribe to the DITL mailing list.

Call for Nominees - 2010 OARC Board of Directors

Now that we have venue and accommodations confirmed for our Fall Workshop in Denver, our attention switches to the AGM and the elections for the Board of Directors. DNS-OARC has two seats on the board which are up for election this year. We are looking for nominations for candidates willing to serve a two-year term on the Board and contribute to the continued growth of OARC. The Board meets monthly, by teleconference, to review DNS-OARC operations.

L-Root now serving "DURZ" signed responses

In case you haven't heard, L.ROOT-SERVERS.NET began serving a DNSSEC-signed root zone today. DNS-OARC has been collecting data during the signed root rollout. The graph below shows how L-root's priming response size has increased during the last hour since it first began serving signed responses:

We're also watching the data below to see if there are noticeable increases in priming query rates after signing:

DITL 2009 Data: Query rates to TLDs with wildcards

Last week someone asked me if the DITL 2009 data could shed any light on the amount of queries sent to TLDs with wildcards. While we do have data from a few TLD operators, it wouldn't really help to answer this question. However, I think we can get a "first-order approximation" by looking at the queries to root nameservers. Note that by looking at queries to the roots, we have no knowledge of client queries that are cache hits and those that are sent to the TLD nameservers due to cached referrals.
