public static long ip2int(String ip) { String[] items = ip.split("\\."); return Long.valueOf(items[0]) < < 24 | Long.valueOf(items[1]) << 16 | Long.valueOf(items[2]) << 8 | Long.valueOf(items[3]);}public static String int2ip(long ipInt) { StringBuilder sb = new StringBuilder(); sb.append(ipInt & 0xFF).append("."); sb.append((ipInt >> 8) & 0xFF).append("."); sb.append((ipInt >> 16) & 0xFF).append("."); sb.append((ipInt >> 24) & 0xFF); return sb.toString();}
