I have noted a number of aircraft coming into the region with the country code being shown as ICAO (special use), upon reviewing the flags.js file I can see that range is 899000…8993FF.
When I do an ICAO lookup of one of the planes i.e. 8991B0 (B-18301) it says it belongs to China Airlines and is registered in Taiwan and states their country range is also 899000…8993FF.
ICAO24-address 8991B0 is from Taiwan TW ] : 899000…8993FF (1024 allocations, 10001001 100100-- --------)
8991B0 hex = 9015728 decimal = 42310660 octal = 10001001 10010001 10110000 binary.
Double checked where air China Airlines is based and it’s not China despite what I thought!
China Airlines (CAL) (Chinese: 中華航空; pinyin: Zhōnghuá Hángkōng) (TWSE: 2610) is the flag carrier and largest airline of Taiwan.
I have updated my flags file, not sure if someone wants to update the one in the latest release.
