what is STUN stun.l.google.com:19302 used for

by

  • STUN servers are used by both clients to determine their IP address
    as visible by the global Internet.If both the peers are behind the
    same NAT , STUN settings are not needed since they are anyways
    reachable form each other . STUN effectively comes into play when the
    peers are on different networks.

  • As we know that webRTC is peer to peer and the ice candidates are
    mandatory in webrtc. ICE functionality can be in any of the two ways
    , STUN and TURN .

  • There are many stun servers provided by google and other sites which
    one could use . You can also setup your own STUn server according to
    rfc5766.

Hope that gives a zest of what and how of stun .
