IPv6 support in NJ

jberwick

What's the status of IPv6 support in southern New Jersey? I have checked every few months for the past two years or so, and the results appear to be the same. My firewall requests and receives a /56 prefix. I carve out a /64 for my inside test network, and this is the traceroute I get: (I always seem to get a prefix inside of 2600:4040:E110::/48)

In the case below, I was assigned 2600:4040:E110:DB00::/56 via PD. My test inside interface ended up at 2600:4040:E110:DB00:FF::1, and my test client on that interface ended up at 2600:4040:E110:DB00:2A3:8EFF:FEEC:E5EB, although I see the same results when trying directly from FF::1.

My traffic gets through my firewall and out into Verizon, but then it dies at hop four every time.

Externally, it looks like there is a BGP announcement covering the /56 I am receiving:

route-views>show ipv6 route 2600:4040:E110:DB00:FF::1
Routing entry for 2600:4040:E000::/36

Trying to reach an address in the /56 from outside of Verizon, however, just loops:

route-views>traceroute ipv6 2600:4040:E110:DB00:FF::1
Type escape sequence to abort.

I get a similar result from any AS I source traffic from.

I can release and request a new prefix but get the same results with any /56 I get assigned.

I have no idea where to go for support for this type of problem. This is on residential fios 1g service.

Normally I would say Verizon's tech support. That would be the best place to report this sort of thing. What you're seeing is a situation where the Netblock you've received is configured locally and can route in and out of your central office, but there is likely a route filter configured on the Verizon backbone which isn't permitting traffic to or from your IPv6 subnet. It's a reasonably quick fix for any network engineer. Route filters are pretty common, and a lot of networks utilize them to prevent subnets that are known to be unallocated within the provider's network, from routing across the backbone.

I just fear that you might run into a problem trying to explain to tech support that the issue isn't with your home network, your own router, or with IPv6 being enabled.

I had this same situation happen with an another Enterprise Fiber provider I use. The Static IPv6 allocation I received for both my router's Transit Address, as well as the /48 block of IPv6 for me to route in my network, was being filtered out at the backbone, but was being properly announced in BGP. A quick call to the provider's NOC with some traceroutes showing the problem, and the routing was fixed within a few hours.
