IP::China - decide whether an internet address is from China


    use IP::China 'chinese_ip';
    if (chinese_ip ('')) {
        print '你好';


The module has only one function:


    my $is_chinese = chinese_ip ('');

Given an internet protocol string (version 4), decide whether it is Chinese or not. The return value is a true value (-1) if the address is from China, and a false value (0) if the address is not from China.


The module will be periodically updated. Allocated addresses for China may change. The script to build updates is included in the git repository for this distribution. Please refer to Makefile.PL for the git repository URL.

The script also includes some errata for the MaxMind list.


The data block as follows:,1814991,6252001,,0,0

is recorded as in China (country code 1814991), but this block seems to belong to Google & not be in China, so this is discounted from the results.

SEE ALSO ^ contains an article and some links to further information.
