GET over IPv6
+++++++++++++

Send SNMP GET request using the following options:

* with SNMPv2c, community 'public'
* over IPv6/UDP
* to an Agent at [::1]:161
* for three OIDs in string form

Functionally similar to:

| $ snmpget -v2c -c public udp6:[::1]:161 1.3.6.1.2.1.1.1.0 1.3.6.1.2.1.1.2.0 1.3.6.1.2.1.1.3.0
