The list of methods to do Long to IP Address are organized into topic(s).

Method

int[]longToIp(long address)
A convenient method that accepts an IP address represented as a long and returns an integer array of size 4 representing the same IP address. 
int[] ip = new int[4];
for (int i = 3; i >= 0; i--) {
    ip[i] = (int) (address % 256);
    address = address / 256;
return ip;
StringlongToIp(long i)
long To Ip 
return ((i >> 24) & 0xFF) + "." + ((i >> 16) & 0xFF) + "." + ((i >> 8) & 0xFF) + "." + (i & 0xFF);
StringlongToIp(long i)
long To Ip 
long ipOnly = i & 0xFFFFFFFF;
long netmask = (long) (i >> NUMBER_OF_BITS_IN_IP);
StringBuffer result = new StringBuffer();
result.append((ipOnly >> TWENTY_FOUR) & X_FF);
result.append(DOT);
result.append((ipOnly >> SIXTEEN) & X_FF);
result.append(DOT);
result.append((ipOnly >> EIGHT) & X_FF);
...
StringlongToIp(long ip)
covert the ip address from decimal to dot formatted 
StringBuilder sb = new StringBuilder(15);
for (int i = 0; i < 4; i++) {
    sb.insert(0, Long.toString(ip & 0xff));
    if (i < 3) {
        sb.insert(0, '.');
    ip = ip >> 8;
return sb.toString();
StringlongToIp(long ip)
long To Ip 
StringBuilder sb = new StringBuilder(15);
for (int i = 0; i < 4; i++) {
    sb.insert(0, Long.toString(ip & 0xff));
    if (i < 3) {
        sb.insert(0, '.');
    ip >>= 8;
return sb.toString();
StringLongToIp(long longIp)
Long To Ip 
StringBuffer sb = new StringBuffer("");
sb.append(String.valueOf((longIp >>> 24)));
sb.append(".");
sb.append(String.valueOf((longIp & 0x00FFFFFF) >>> 16));
sb.append(".");
sb.append(String.valueOf((longIp & 0x0000FFFF) >>> 8));
sb.append(".");
sb.append(String.valueOf((longIp & 0x000000FF)));
...
StringlongToIp(long longValue)
long To Ip 
int[] byteIPAddress = { 0, 0, 0, 0 };
for (int i = 3; i >= 0; i--) {
    byteIPAddress[i] = (int) (longValue % 256);
    longValue = longValue >> 8;
String returnValue = new String(
        byteIPAddress[0] + "." + byteIPAddress[1] + "." + byteIPAddress[2] + "." + byteIPAddress[3]);
return returnValue;
...
StringlongToIp(String ip)
Converts a String IP address to a long String representation. 
Long ipLong = Long.valueOf(ip);
StringBuilder result = new StringBuilder(15);
for (int i = 0; i < 4; i++) {
    result.insert(0, Long.toString(ipLong & 0xff));
    if (i < 3) {
        result.insert(0, '.');
    ipLong = ipLong >> 8;
...
StringlongToIpAddress(long ip)
Returns the 32bit dotted format of the provided long ip. 
if (ip > 4294967295l || ip < 0) {
    throw new IllegalArgumentException("invalid ip");
StringBuilder ipAddress = new StringBuilder();
for (int i = 3; i >= 0; i--) {
    int shift = i * 8;
    ipAddress.append((ip & (0xff << shift)) >> shift);
    if (i > 0) {
...
StringlongToIPv4(final long ipaddress)
Convert a long to an IP Address, as four dotted octets. 
final String SOURCE = "NetworkScannerHelper.longToIPv4() ";
final int octet1;
final int octet2;
final int octet3;
final int octet4;
final String strIP;
octet1 = (int) ((ipaddress & 0x00000000FF000000L) >>> 24);
octet2 = (int) ((ipaddress & 0x0000000000FF0000L) >>> 16);
