Detailed Description

Guessing home router based on DNS query with default suffix.

  • Request

    The end host sends a DNS query that is equivalent to this command:

    dig +search +short +cmd +tries=2 +ndots=10 _ndn._udp srv
  • Response

    The DNS server should answer with an SRV record that contains the hostname and UDP port number of the NDN router.
