Problem
Displaying and Searching for IPV4 addresses in IPV6 format.
Solution
There are two distinct methods IBM Tealeaf uses for converting an IPV4 address into an IPV6 address.? Displayed IPV6 values follow the IETF standard.? Indexing and searching does not.? This dichotomy allows greater flexibility for the search mechanism.? It allows searching for a range of values in any of the octets of the IPV4 address.
Given an IPV4 address A.B.C.D each of the four octets are represented by a decimal number between 0 and 255. The hexadecimal (hex) equivalent is between 00 and FF.? Refer to these hexadecimal representations as AH BH CH and DH.? In this case the IPV6 address displayed in the Request is:

0000:0000:0000:0000:0000:FFFF:AHBH:CHDH
which matches the format specified in the IETF standard.? A Portal search for the IPV4 address A.B.C.D is correctly processed but the query string it produces uses a Tealeaf-internal IPV6 format of:
0000:0000:0000:0000:00AH:00BH:00CH:00DH.?
This format is also used when searching with?RealiTea Viewer (RTV) for an IPV6 Client IP address.? Searching for the IPV4 address in IPV4 format requires using the Client IP (legacy) search criterion.? Use only the IPV4 format for searching both from the Portal and from RTV.? This means using RTV Client IP (legacy) criterion rather than the Client IP one.
