Fiber Telecom is hosting a local AS112 instance advertised to our upstream and peering connections.
We are one of many volunteer operators participating in the AS112 project, which helps reduce the load on IANA blackhole servers in answering DNS queries for addresses reserved for private use.
For more information visit www.as112.net.
The Messages by Opcode plot shows
the breakdown of OPCODE values, other than QUERY, in DNS queries.
Since QUERY is the most common opcode, its inclusion here would
dominate the plot. Some of the less common opcodes are:
- IQUERY - An "inverse query" which has been deprecated
in favor of the PTR query type.
- STATUS - A server status request.
- NOTIFY - Allows master servers to inform slave servers when a zone has changed.
- UPDATE - Add or delete RRs or RRsets from a zone.
- Other - All other opcode values, legitimate or not.
Click on the legend to view the queries for a specific opcode.
