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

[Claus Klein]

Hello Jochen,

thanks for your help, it works now fine.

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

I tried to do it as a new IpAddress class function:

What do you think to add something like that  to the snmp++ library?
