项目中需把IPV6 转成数字 方便保存数据库，利于节省空间和加速查询。废话不多说贴代码： JavaScript: BigInteger.js
//ipv6 转38为数字 function ip2long6(ip_address) { var parts = []; ip_address.split(':').forEach(function(it) { var bin = parseInt(it, 16).toString(2); while (bin.length < 16) { bin = '0' + bin; } parts.push(bin); }); var bin = parts.join(''); //需要引入js文件，我会在附件贴上 return bigInt(bin, 2).toString(); } /** * 位数补偿 * @param dividend * @param divisor * @returns {{quotient: (string|*), remainder: *}} */ function divide(dividend, divisor) { var returnValue = ''; var remainder = 0; var currentDividend = 0, currentQuotient; dividend.split('').forEach(function(digit, index) { // use classical digit by digit division if (currentDividend !== 0) { currentDividend = currentDividend * 10; } currentDividend += parseInt(digit); if (currentDividend >= divisor) { currentQuotient = Math.floor(currentDividend / divisor); currentDividend -= currentQuotient * divisor; returnValue += currentQuotient.toString(); } else if (returnValue.length > 0) { returnValue += '0'; } if (index === dividend.length - 1) { remainder = currentDividend; } }); return { quotient: returnValue.length === 0 ? '0' : returnValue, remainder: remainder, }; } /** * 数字转ipv6 * @param input * @param base * @returns {string} */ function convertToIPv6(input, base) { base = base || 10; var blocks = []; var blockSize = Math.pow(2, 16); // 16 bit per block while (blocks.length < 8) { var divisionResult = divide(input, blockSize); // The remainder is the block value blocks.unshift(divisionResult.remainder.toString(base)); // The quotient will be used as dividend for the next block input = divisionResult.quotient; } return blocks.join(':'); }PHP代码： 注：需要打开php.ini 里面的 extension=php_gmp.dll 如果没有dll 请自行下载。如果你是linux 请自行编译so
