TL;DR: I want to snoop on IPv6 or somehow detect whether my ISP is offering SLAAC, DHCPv6, or anything else IPv6 related on my line. What Mikrotik commands can help me do that? My ISP is incredibly clueless about IPv6. See below.
My ISP (Verizon Business) is pretty terrible at IPv6. Because I pay them for static IPv4, they say they have no support for IPv6 on my line at all. Their residential customers in this area get a random /64 assigned dynamically (I think, that's what I remember when I was on residential 6 years ago). I spent a couple hours on the phone with support, and they claim that neither dynamic nor static IPv6 is available in my area because I am business plus static IPV4. Any other combination (business + dynamic, residential) would have some amount of IPv6. I can see why this is hard: I'm right outside Ashburn, VA, where you know, there really isn't much Internet or advanced networking. And there's only a handful of tech companies in the area that you've never heard of.
Let's ignore, for a moment, that if you search ipv6 verizon business the number one link (on DuckDuckGo, anyway) is this PDF of ipv6 FAQs from Verizon. And that FAQ discusses IPv6 for Verizon Business customers. It says:
Q: Does Verizon support IPv6?
Yes, for Dynamic IP addressing, which most of our Fios Business Internet customers use, we support both IP4v and IPv6, often referred to as “dual stack”. Support for Static IPv6 addresses is in the process of being rolled out across our footprint. Please note that not all routers support IPv6.
If I view my account online, I can see all my IPv4 parameters but no parameters for IPv6. I set up a DHCPv6 client on my WAN interface, and I've tried info, prefix, and address requests. Nothing ever changes. It just shows STATUS:SEARCHING... in webmin.
Are there any other tricks I can try to figure out whether any IPv6 is offered, and if so, what the parameters are? I don't care that my v4 is static and my v6 might be dynamic. That's fine for now.
