Unregistered but busy: CCProxy's HTTP proxy, .NET net.tcp services, and assorted alternate web ports.
IANA has no assignment for 808, but it is one of the more commonly open ports in this range. Nmap names it "ccproxy-http" after CCProxy, a Windows HTTP/FTP/Gopher proxy that uses it by default, and an open 808 on a Windows host is often exactly that. It is also the default port for Microsoft's net.tcp:// WCF endpoints and the Net.TCP Port Sharing Service, and a popular hand-picked alternate HTTP port for internal web apps. Which of these you have is decided entirely by fingerprinting, since the three speak completely different protocols.
Do not expose
An open proxy on 808 will be found and abused for relayed traffic within days; WCF endpoints are internal RPC. Neither belongs on a public IP unauthenticated.
