SkyDNS's Features

  • You announce your service by submitting JSON over HTTP to SkyDNS with information about your service. This information will then be available for queries either via DNS or HTTP.
  • SkyDNS requires that services submit an HTTP request to update their TTL within the TTL they last supplied. If the service fails to do so within this timeframe SkyDNS will expire the service automatically. This will allow for nodes to fail and DNS to reflect this quickly.
  • You can find services by querying SkyDNS via any DNS client or utility. It uses a known domain syntax with wildcards to find matching services.
