A website (with custom TCP server) in 1 IPv4 datagram!

To make the biggest-smallest site, we consider the most limiting step among TCP segments, IP datagrams, Ethernet frames, HTTP response...

In RFC 6691, the max size (in bytes) for a TCP segment is the IP max datagram size (576) minus 40 for TCP&IP headers, leaving 536 for HTTP & content.

In RFC 2616 the minimal valid HTTP 1.1 response with DEFLATE compression is: HTTP/1.1 200 OK\r\nContent-Encoding: deflate\r\n\r\n: 46 bytes for HTTP leaves 490 for content.

This text & HTML (using minimal headers) is 482 bytes! Visit aadrake.com for more!
