Known IP address and port blocks by country

The current (00/6/30) status of blocked/open TCP ports is:

UAE
• blocked: 80, 81, 119, 666, 800, 1080, 3128, 6776, 7175, [8001-8008], [8080-8090], 8421, 8888, 10080, 12053, 12345, 12346, 20034
• open: all the rest below 28000; almost all the rest above 28000
• unknown: many above 28000 were not checked
• After the routing debacle of May, 00 it appears that the port blocking is dependent on the (dynamic) route chosen to your destination address. Some of the ports above are no longer blocked for certain destinations. It is not now possible for me to guarantee any of the above information, since it depends on the time of day, your address when you log on, your destination etc. The ports which may be sometimes open/sometimes closed which I have noticed are: 81, 8001 and maybe others.

In addition to the above port blocks, some IP addresses are blocked (again, let me know if there are changes or errors in the list). I can't think of a way to tell if these are blocked by the UAE, or by the destination; if someone can suggest a test, i'd be happy:

• 132.250.196.3 #the onion router proxies (onion-router.nrl.navy.mil)
• 209.166.17.* #the whole range, I think. These are the noproxy proxies (and all their different names). Also blocks the name servers!
• net2phone call server addresses

Saudi Arabia
• blocked: 80, 81, 119, 1080, 3128, 6588, 8000, 8040, 8080, 8965, 9000, 9080, 10080
• open: 21, 22, 23, 82, 83, 856, 880, 3129, 4147, 6532, 7036, 8041, 8046, 8081, 8227, 8583, 8802, 10000, 15514
• unknown: many more

Qatar
• blocked: 80
• open: 8080

Kuwait
• open: all?
• blocked: none?
• A transparent proxy on port 80 censors Qualitynet users - just pick a proxy on any other port.

China - 163 network
• blocked: none?
• open: 25, 110, 119

China - 169 (domestic) network
• blocked: none (?)
• open: all (?)
• none are useful, because the 169 network is in private address space. Proxies or NAT are necessary.

Singapore
• blocked: none?
• open: 80, 8080, 3128 - all?
• private address space?

Please let me know if you can add to the list, or if there's something wrong in there.
