<p><b>New page</b></p><div>= How do I specify IPv6 addresses in tools command line arguments? =<br />
<br />
IPv6 addresses pose a particular problem for the Net-SNMP command line tools, which parse host names into pieces. In particular, normally if you specify a simple host name, it assumes you want UDP in IPv4 on port 161. IE, these two commands are actually the same (by default):<br />
<br />
snmpget 127.0.0.1 sysUpTime.0<br />
snmpget udp:127.0.0.1:161 sysUpTime.0<br />
<br />
However, for IPv6 this causes a problem because IPv6 addresses also use a colon to separate addressing parts. Thus you need to enclose the address in square brackets ( [ and ] ). Because most shells use these brackets too, you also likely need to quote it:<br />
<br />
snmpget 'udp6:[::1]:161' sysUpTime.0</div>Wes
