I'm trying to understand the network I'm part of. It has a couple thousand computers and the backbone routers are supposed to be IPv6, but the firewalls are not, thus there is a hypothetical IPv6 capability, but no routing is possible. I talked to a network admin and he said it had something to do with the firewalls not being IPv6 capable or not routing as fast with IPv6. Does anyone know what firewalls (I don't know anything more specific than that) can have to do with a local network and IPv6?
When I dig the domain of my organization (when I'm in the local network), I get DNS records which also include AAAA records for the nameservers (I don't see these AAAA records when I google the DNS records for the site). But there is no IPv6 routing possible and the host itself does not have a AAAA records. Do you know what are things organizations need to do to migrate their servers to IPv6? Do you need to change any hardware to make this possible if the routers already support IPv6?
