IRC also allows you to send files by using DCC.

  Not sure why this is downvoted, DCC is direct connection which bypasses the server, p2p.

    Likely because it needs a IRC server to set up the handshake, and the exposure of IP addresses. Never mind that DCC and NAT don't mix well.
    • dijit 9y ago
      No different than hitting a webserver. IRC networks cloak your IP address. I agree about NAT, but that doesn't negate the fact that it was peer to peer that worked for over a decade.

      P2P is impossible without exposure of your IP address, for hopefully obvious reasons.

  Complicated with NAT and IPv4/IPv6 mismatches.
