TCP and UDP ports and protocols used by Apple TV

Networked devices like your Mac, PC, and Apple TV communicate with each other using specific communication channels known as TCP and UDP ports. Learn about the ports used by Apple TV.

Apple TV uses these network ports for communications on your network:

  • UDP port 123 is used to communicate with a network time server.
  • TCP port 3689 is used to communicate with iTunes using the iTunes Library Sharing feature.
  • UDP port 5353 is used to automatically find computers with iTunes on your network using Bonjour.
  • TCP port 80 is used to communicate with podcast servers.
  • TCP port 80 and 443 are used to communicate with the iTunes Store securely over the Internet.
  • TCP and UDP port 53 are used for DNS.

These are well-known ports used by Apple products, like iTunes. If you can use all the features of iTunes, these ports are likely already open on your firewall or NAT router.

These ports might also be used by other services like YouTube and Flickr.
