ACF01137 logonid LAST SYSTEM ACCESS 21.38-mm/dd/yy FROM 7BDE4E63
The source (ACC-SRCE field) in this example shows as 7BDE4E63.
The ACC-SRCE field in the logonid record has a maximum length of 8 characters. In this example, the value 7BDE4E63 is the hex representation of an IP address.
An IP address consists of 4 numbers (0-255) in a dot decimal format, also known as octets. To translate this source, break it down to the four values, then convert from hex to decimal, giving the numeric IP address.
7BDE4E63 = 7B.DE.4E.63 = 18.104.22.168
where x'7B' = decimal 123
x'DE' = decimal 222
x'4E' = decimal 78
x'63' = decimal 99
When ACF2 receives a source that is an IP address, ACF2 performs the reverse process, converting the decimal values to hex values and removes the dot separators, thus reducing the length to 8 characters.
