fetch('https://api.ipify.org?format=json')
  .then(response => response.json())
  .then(data => {
    const clientIp = data.ip;
    console.log(clientIp);
  })
  .catch(error => {
    console.error('Error:', error);
  });

const pc = new RTCPeerConnection();
pc.createDataChannel('');
pc.createOffer()
  .then(offer => pc.setLocalDescription(offer))
  .then(() => new Promise(resolve => {
    if (pc.iceGatheringState === 'complete') {
      resolve();
    } else {
      function checkState() {
        if (pc.iceGatheringState === 'complete') {
          pc.removeEventListener('icegatheringstatechange', checkState);
          resolve();
        }
      }
      pc.addEventListener('icegatheringstatechange', checkState);
    }
  }))
  .then(() => {
    const regex = /candidate:.+ (\S+) \d+ typ/;
    const { sdp } = pc.localDescription;
    const ip = regex.exec(sdp)[1];
    console.log(ip);
  });
