2016 OARC Elections and AGM
The DNS-OARC 2016 Annual General Meeting will take place on the 15th of October at the start of the OARC25 Workshop, in Dallas, Texas, USA.
Mitigating DNS Denial of Service Attacks
The DNS protocol is, unfortunately, an effective Denial-of-Service attack vector for a few reasons:
- DNS generally uses the connectionless User Datagram Protocol (UDP) as its transport.
- Many autonomous systems allow source-spoofed packets to enter their network.
- There is no shortage of Open Resolvers on the Internet.
DNS-OARC facility relocation, 14th-18th May 2016
Please be advised that DNS-OARC will be relocating its equipment and services to a new facility during next week starting this Saturday, May 14th through Wednesday the 18th. There will be multiple sporadic outages during this time affecting ALL services and ALL systems as a result.
RSSAC 002
ICANN's Root Server System Advisory Committee has recently defined two standards, including RSSAC 002 , designed to obtain a baseline of the metrics for the Root Zone, specifically so that root operators can detect and mitigate any abnormalities in the performance of the DNS Root Server System as it continues to grow and develop.
OARC's DNS Reply Size Test Server
2023-06-01: This service has been deprecated in favor of Check My DNS.
Recent increases in DNSSEC deployment are exposing problems with DNS resolvers that cannot receive large responses. The maximim reply size between a DNS server and resolver may be limited by a number of factors:
OARC's TLDmon Service
OARC's TLDmon uses Nagios to monitor operational characteristics of authoritative nameservers for the Root Zone and all Top Level Domains. TLDmon checks for authoritative answers, EDNS support, lame delegations, consistent NS RR sets, open resolvers, expired RRSIGs, matching serial numbers, and TCP support. As the Domain Name System continues its evolution, it becomes increasingly important that these critical nameservers are configured correctly.

DNS Looking Glass Information
There are a number of DNS Looking Glass sites around the Internet that will allow anyone to send a DNS query from that location. Looking Glasses are of particular use in the case of troubleshooting a problem with a DNS zone that is served from an anycasted service. In the event of a problem with the service, the view of a zone can be very different from distant places on the Internet. Here is a list of some of the known looking glass sites around the Internet:
