[AGENT++] IpAddress: how to create a Hex-String instead a String?

[Claus Klein]

Hallo List,

I have a simple table with an agent++::IpAddress, but when I read this  
OID, the result is NOT encoded as I expected

This is how I fill this value:

            IpAddress _ipAddr("::1");
             row->get_nth(nNetSnmpHostAddress)- 
 >replace_value(OctetStr(_ipAddr).clone());

And that is what I get:

--- snip ---

00 01 A2 00

NET-SNMP-EXAMPLES-MIB::netSnmpHostAddress."loopback" = STRING:  
"0000:0000:0000:0000:0000:0000:0000:0001"
SNMP-TARGET-MIB::snmpTargetAddrTAddress.'internal0' = Hex-STRING: 00  
00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 A2 00


As you can see, the TargetAddressTable is more compact for this simple  
ipv6 localhost address!

Too, IpAddress::get_printable() should get the string as "::1" in this  
case.
Is it possible to control this?


Any good idea would help.

With regards,
Claus
