DNS test definition

DNS test. Means one non-­‐recursive DNS query sent to a particular “IP address” (via UDP or TCP). If DNSSEC is offered in the queried DNS zone, for a query to be considered answered, the signatures must be positively verified against a corresponding DS record published in the parent zone or, if the parent is not signed, against a statically configured Trust Anchor. The answer to the query must contain the corresponding information from the Registry System, otherwise the query will be considered unanswered. A query with a “DNS resolution RTT” 5 times higher than the corresponding SLR, will be considered unanswered. The possible results to a DNS test are: a number in milliseconds corresponding to the “DNS resolution RTT” or, undefined/unanswered.

If DNSSEC is offered in the queried DNS zone, for a query to be considered answered, the signatures must be positively verified against a corresponding DS record published in the parent zone or, if the parent is not signed, against a statically configured Trust Anchor. The query shall be about existing domain names. The answer to the query must contain the corresponding information from the Registry System, otherwise the query will be considered unanswered. If the answer to a query has the TC bit set, the query will be considered unanswered. A query with a “DNS resolution RTT” 5-times higher than the corresponding SLR, will be considered unanswered. The possible results to a DNS test are: a number in milliseconds corresponding to the “DNS resolution RTT” or, undefined/unanswered. Measuring DNS parameters. Every minute, every DNS probe shall make an UDP and a TCP “DNS test” to each of the public-DNS registered “IP addresses“ of the name servers of the domain named being monitored. If a “DNS test” gets unanswered, the tested IP will be considered as unavailable for the corresponding transport (UDP or TCP) from that probe until it is time to make a new test. The minimum number of active testing probes to consider a measurement valid is 20 at any given measurement period, otherwise the measurements will be discarded and will be considered inconclusive; during this situation no fault will be flagged against the SLRs. Placement of DNS probes. Probes for measuring DNS parameters shall be placed as near as possible to the DNS resolvers on the networks with the most users across the different geographic regions; care shall be taken not to deploy probes behind high propagation-delay links, such as satellite links.

Examples of DNS test in a sentence

  • The integration tests use Deckard, the DNS test harness.$ make check-integration Note that the daemon and modules must be installed first before running integration tests, the reason is that the daemon is otherwise unable to find and load modules.Read the documentation for more information about requirements, how to run it and extend it.

Related to DNS test

  • RDDS test Means one query sent to a particular “IP address” of one of the servers of one of the RDDS services. Queries shall be about existing objects in the Registry System and the responses must contain the corresponding information otherwise the query will be considered unanswered. Queries with an RTT 5 times higher than the corresponding SLR will be considered as unanswered. The possible results to an RDDS test are: a number in milliseconds corresponding to the RTT or undefined/unanswered.

  • EPP test Means one EPP command sent to a particular “IP address” for one of the EPP servers. Query and transform commands, with the exception of “create”, shall be about existing objects in the Registry System. The response shall include appropriate data from the Registry System. The possible results to an EPP test are: a number in milliseconds corresponding to the “EPP command RTT” or undefined/unanswered.
