interceptAddrDial method

@override bool interceptAddrDial(PeerId peerId, MultiAddr addr)

Tests whether we're permitted to dial the specified multiaddr for the given peer.

This is called by the network implementation after it has resolved the peer's addrs, and prior to dialling each.

Implementation

@override
bool interceptAddrDial(PeerId peerId, MultiAddr addr) {
  // Check if the peer is blocked
  if (isPeerBlocked(peerId)) {
    _logger.fine('Blocked peer dial: $peerId');
    return false;
  }

  // Check if the address is blocked
  if (isAddrBlocked(addr)) {
    _logger.fine('Blocked address dial: $addr');
    return false;
  }

  // Check if the address is in a blocked subnet
  if (isAddrInBlockedSubnet(addr)) {
    _logger.fine('Blocked subnet dial: $addr');
    return false;
  }

  return true;
}
