In discussions about IP address banning, IP 82.148.97.69 is often cited as an example. According to Wikipedia, this IP address is the public address of "the entire nation of Qatar". There are two things I don't quite understand:
Why does Qatar use a single IP address when it was given more than 800,000 IP addresses by IANA? Did they sell all other IP addresses to someone, or do they use these IP addresses for something non-public?
With a single public IP address, isn't the proxy server limited to 65,536 simultaneous connections (by the number of available TCP ports)? How do they deal with this limitation? Or is the whole country limited to 65,536 simultaneous Skype calls?
EDIT
Since the answer and the comments suggest that the initial statement is false, I wonder why would Wikipedia make such claims in the first place. Is it conceivable that back in 2009 everyone in Qatar had the same public IP address?
