Pros/Cons of enabling IPv6

  • SNBForums Code of Conduct

    SNBForums is a community for everyone, no matter what their level of experience.

    Please be tolerant and patient of others, especially newcomers. We are all here to share and learn!

    The rules are simple: Be patient, be nice, be helpful or be gone!

In the end, the cons won. The main con being that having IPv6 enabled doubled the size of my Diversion blockinglist to over a million entries (~500K IPv4, ~500K IPv6). dnsmasq was using a lot of memory (relative to before) and was slow to startup.

So it wasn't a big issue that deterred me, but an uncomfortable annoyance with the parallel IPv4/IPv6 universes.

Yea I have to say the biggest issue I have with IPV6 is IPTables and the overall routing of it and lack of stable static addressing support (*** takes along time to properly configure stateful).

@dave14305 , have you tried enabling IPV6 again? I'm looking into enabling it again but my current setup is working flawlessly including gaming. Microsoft recommends enabling IpV6 for better connectivity experience for the xbox and supposedly "lower" pings but I wonder how true this is.

Ipv6 works great if you are able to run it in a stateless condition complimentary to your ipv4. The only drawback is it leaves alot of openings as ipv6 relies heavily on not being blocked in order to function properly.

Note your isp has to have a good implementation for it to be any real benefit to you.

I imagine they are claiming some servers are only accessible via ipv6 and/or that ipv6 could bypass your carriers Nat so could be faster.
 
I ran IPv6 for a few years only to recently disable it.
  • Some devices still don't support it (ESP8266 type stuff) and some hotspots.
  • It's objectively slower.
  • It adds additional complexity to the network.
  • It requires opening your network up to get full compliance.

Since disabling IPv6 I haven't missed it at all.

When we get to a place where we'll need to run it, there's lots of work yet to be done to achieve full compliance. Most environments fail the numerous IPv6 browser tests...

Been running v6 for years. I run a few servers here and they are happy with incoming v6.
I have no idea why I'd want to disable it.
If it is the size of block lists, run a pihole if possible instead of relying on your router to do it. Works fine here.

Running a server is one thing. Managing a home network, which is mainly consuming content rather than serving it, is another. What is a reason that a home or office network would run IPv6?

When I was on cable internet my provider had ipv6 and I had no issues with anything running dual stack.

The biggest proponent against ipv6 support is the technology industry itself, shipping products with claims of supporting ipv6,but only providing half the functionality or outdated binaries with limited support for the platform.
 
What did it do for you?

Nothing really my experience didn't really change from ipv4 only to dual stack based on what I do on the internet.
 
IPv6-just a false sense of security thinking it was "better" somehow. It worked fine on cable but I had to go back to v4 when changed to fiber which doesn't support it.
