DNS Benchmark 1.2.3925.0

Add

A small software to measure the performance of different DNS providers. GRC's DNS Benchmark performs a detailed analysis and comparison of the operational performance and reliability of any set of up to 200 DNS nameservers (sometimes also called resolvers) at once. When the Benchmark is started in its default configuration, it identifies all DNS nameservers the user's system is currently configured to use and adds them to its built-in list of publicly available “alternative” nameservers. Each DNS nameserver in the benchmark list is carefully “characterized” to determine its suitability — to you — for your use as a DNS resolver. This characterization includes testing each nameserver for its “redirection” behavior: whether it returns an error for a bad domain request, or redirects a user's web browser to a commercial marketing-oriented page. While such behavior may be acceptable to some users, others may find this objectionable.

Features:

  • For each of up to 200 DNS nameservers, using the Internet's most popular top-50 domain names, independently measures, charts, statistically analyzes, reports (and optionally exports):
    • Cached lookups – the time to return a domain name that is already in the resolver's name cache.
    • Uncached lookups – the time to return a sub-domain name that is not already in the resolver's name cache.
    • Dotcom lookups – the time to consult the nameserver's chosen dotcom resolver(s) for a dotcom name.
    • Reliability – the number of queries not replied to (lost) during the benchmark.
    • Rebinding protection – whether the resolver blocks non-routable private IP addresses.
  • Optionally verifies whether nameservers provide DNS security (DNSSEC) record authentication.
  • When using a list of (provided) DNSSEC-signed domains, benchmarks DNSSEC authentication performance.
  • Graphs and compares all four benchmark parameters with an easy-to-read bar chart.
  • Builds a customized list of the fastest performing (for you) top 50 resolvers, located anywhere in the world, selected from a master list of more than 4,800 possible known resolvers.
  • On-the-fly hierarchical sorting of performance results by cached (default) or uncached performance.
    (Sorting is “hierarchical” because cached (or uncached) performance is sorted first, followed by uncached (or cached), then by dotcom last.)
  • Auto-scaled bar chart that can be manually overridden for chart-to-chart comparison.
  • Pop-up value “inspector” (left click in nameserver list) displays precise values on bar chart.
  • Detailed tabular results report.
  • Fully detailed, locale-aware (internationalized), CSV results export.
  • Automatic logging to a CSV file for long-term background results monitoring and collection.
  • Simultaneously compares the performance and reliability of up to 200 DNS nameservers.
  • Determines network name (reverse DNS), ownership, and operational status for each nameserver.
  • Determines whether nameservers intercept and redirect bad domain names.
  • Comprehensive, heuristic “Conclusions” generation summarizes all results and suggests useful system changes, if any, in easily readable English.
  • All results are analyzed for statistical significance with a 95% confidence threshold.
  • Bottom of tabular data page contains built-in quick-reference “reminder” help.
  • The built-in top-50 domains list is user-replaceable to allow more/less statistical significance, and for support of DNSSEC record authentication.
  • .INI files containing sets and subsets of nameservers to benchmark can be added, removed, and saved.
  • Special “dnsbench.ini” file is auto-loaded, if present, to always override built-in nameserver list.
    (This supports the use of customizable personal nameserver lists for special applications.)
  • At start-up, tests for the presence of, and deliberately “triggers”, any outbound-blocking personal firewalls to allow Internet access exceptions to be provided before testing begins.
  • Internet connectivity aware – verifies unimpeded Internet connectivity before testing and gracefully handles possible loss of Internet connectivity during testing.
  • Bar chart results can be copied to the system clipboard or saved in BMP or compressed PNG format for storage or sharing.
  • Built-in self-screen capture to BMP or compressed PNG file.
  • All benchmark pages and tabs can be copied to the system clipboard or saved to files as text, rich-text, or images as appropriate.

Compzets Tip: With this software, you can compare different DNS providers and select the fastest one so as to browse web sites much more faster than before. You can search in google "How to change DNS in windows".
