[AGENT++] IPv4 vs IPv6 difference?

this is right in theory, because there aren't many people using snmp++
with IPv6.

If you want to send notifications you have to define
USE_LISTEN_ADDRESS_FOR_SENDING_TRAPS, as otherwise
SnmpRequest::get_new_snmp() will just create a Snmpx object through
Snmpx(status, 0) which defaults to IPv4.

If you're using add_vX_trap_destination(), you have to apply the patch
below.
