Convert StringIP Address to LongIP Address
|
| |
Converts a string ip address ("192.168.0.1") to a Long number
(3232235521). One of the reasons to do this would be to store IP addresses in
databases. Numbers greatly reduce the size required to store this information.
Inputs: asNewIP - String IP address ("192.168.0.1") to convert to a number.
Returns: Returns a Long Integer representing the IP address (3232235521)
Assumes: This function assumes that your IP address has 4 integers delimited by decimals and that the numbers range from 0 to 255.
Function
CLngIP(ByVal asNewIP)
Dim
lnResults
Dim
lnIndex
Dim
lnIpAry
'
Split the IP address using the dot as a delimiter
lnIpAry = Split(asNewIP,
".", 4)
'
Loop through Each number In the IP address
For
lnIndex = 0 To 3
'
If we are Not working With the last number...
If
Not lnIndex = 3 Then
'
Convert the number To a value range that can be parsed from the others
lnIpAry(lnIndex)
= lnIpAry(lnIndex) * (256 ^ (3 - lnIndex))
End
If
'
Add the number To the results
lnResults
= lnResults + lnIpAry(lnIndex)
Next
' If
storing number within an Access Database,
'
The variable Type "Long" ranges from -2147483648 To 2147483647
'
You will need To subtract 2147483648 from the number
'
before querying the database.
'
lnResults = lnResults - 2147483648
'
Return the results
CLngIP = lnResults
End Function
