Leverage free, libre, open source software to monitor your network with LibreNMS. Enable SNMP, ICMP, and LLDP/CDP/XDP data collection to gather, aggregate, and report network information all with open source tooling, using Podman Quadlets
Another post in the records for the tech blog, this time all about opensource network monitoring with LibreNMS!
You are absolutely correct, thank you. Sadly a bunch of devices still don’t support it, even in 2025 (like my microtik switch) for example. I will absolutely add a note about that though, thank you!
And IPv6 was codified in RFCs and first addresses issued in 1999 but look where we are now. I’d bet your corporate network doesn’t use IPv6 still. It’s unfortunate, but sometimes the wheels of change are slow.
Hey good for you, that’s awesome! My home network is also dual stacked.
You’re right about the apples to oranges comparison, but it’s not so wildly off, because the commentary is on adoption of new standards, regardless of bolt-on “fixes.” Unauthenticated SNMP went through three revisions prior to adding authentication and encryption support.

Updated the post to reflect your feedback here. Thank you!
Really? SNMPv3 was ratified in 1998. How does anyone take them seriously without it?

My home, work, and mobile networks are all dual stacked.
This is a difference in kind. IPv4 live was extended with Nat and cgnat, but nothing equivalent came for snmp.
