lambaliciousIt's easier to remember the IPs of good DNSes, too.
I think it’s worth taking the time to learn IPv6 property. If you have a good understanding of IPv4 it shouldn’t take you more than an afternoon.
Eliminating NAT and just using firewall rules (ie what NAT does behind your back) is incredibly freeing.
I don’t get people complaining about typing out IPs. I like to give all of my clients full FQDNs but you don’t have to. Just using mDNS would be enough to avoid typing a bunch of numbers.
Maybe I have Stockholm Syndrome, but I like NAT. It’s like, due to the flaws of IPv4 we basically accidentally get subnets segmented off, no listening ports, have to explicitly configure port forwarding to be able to listen for connections, which kinda implies you know what you’re doing (ssshh don’t talk about UPnP). Accidental security of a default deny policy even without any firewalls configured. Haha. I’m still getting into this stuff though, please feel free to enlighten me
Every time I see a defense of IPv4 and NAT, I think back to the days of trying to get myself and my roommate to play C&C: Generals together online, with a 2v2 game, with one of us hosting. Getting just the right combination of port forwarding working was more effort than us playing C&C: Red Alert on dial up when we both lived at home.
With IPv6, the answer is to open incoming traffic on the port(s) to the host machine (or just both since the other guy is might host next time). With IPv4, we have to have a conversation about port forwarding and possibly hairpin routes on top of that. This isn’t a gate for people “who know what they’re doing”, it’s just a bunch of extra bullshit to deal with.
