IPv6アドレスをIP番号に変換する式

Question

IPV6のアドレスをIPに変換する式を探しています。これは、私たちが持っているgeoipの位置情報とマップするために必要です。

入力IPV6アドレス：IP番号を変換2001:0db8:0000:0000:0000:ff00:0042:8329

から取られた番号にIPv6アドレスを変換するために、複数の言語でのサンプルコードです

PHP

$ipv6 = '2404:6800:4001:805::1006'; 
$int = inet_pton($ipv6); 
$bits = 15; 

$ipv6long = 0; 

while($bits >= 0){ 
    $bin = sprintf("%08b", (ord($int[$bits]))); 

    if($ipv6long){ 
     $ipv6long = $bin . $ipv6long; 
    } 
    else{ 
     $ipv6long = $bin; 
    } 
    $bits--; 
} 

$ipv6long = gmp_strval(gmp_init($ipv6long, 2), 10); 

のJava

java.math.BigInteger Dot2LongIP(String ipv6) { 
    java.net.InetAddress ia = java.net.InetAddress.getByName(ipv6); 
    byte byteArr[] = ia.getAddress(); 

    if (ia instanceof java.net.Inet6Address) { 
     java.math.BigInteger ipnumber = new java.math.BigInteger(1, byteArr); 
     return ipnumber; 
    } 
} 

C＃

string strIP = "2404:6800:4001:805::1006"; 
System.Net.IPAddress address; 
System.Numerics.BigInteger ipnum; 

if (System.Net.IPAddress.TryParse(strIP, out address)) { 
    byte[] addrBytes = address.GetAddressBytes(); 

    if (System.BitConverter.IsLittleEndian) { 
     System.Collections.Generic.List byteList = new System.Collections.Generic.List(addrBytes); 
     byteList.Reverse(); 
     addrBytes = byteList.ToArray(); 
    } 

    if (addrBytes.Length > 8) { 
     //IPv6 
     ipnum = System.BitConverter.ToUInt64(addrBytes, 8); 
     ipnum <<= 64; 
     ipnum += System.BitConverter.ToUInt64(addrBytes, 0); 
    } else { 
     //IPv4 
     ipnum = System.BitConverter.ToUInt32(addrBytes, 0); 
    } 
} 

VB.NET

Dim strIP As String = "2404:6800:4001:805::1006" 
Dim address As System.Net.IPAddress 
Dim ipnum As System.Numerics.BigInteger 

If System.Net.IPAddress.TryParse(strIP, address) Then 
    Dim addrBytes() As Byte = address.GetAddressBytes() 

    If System.BitConverter.IsLittleEndian Then 
     Dim byteList As New System.Collections.Generic.List(Of Byte)(addrBytes) 
     byteList.Reverse() 
     addrBytes = byteList.ToArray() 
    End If 

    If addrBytes.Length > 8 Then 
     'IPv6 
     ipnum = System.BitConverter.ToUInt64(addrBytes, 8) 
     ipnum <<= 64 
     ipnum += System.BitConverter.ToUInt64(addrBytes, 0) 
    Else 
     'IPv4 
     ipnum = System.BitConverter.ToUInt32(addrBytes, 0) 
    End If 
End If
