Bryan DriskellHOST
Christian Gray, I talked about, could have a big day.
Bryan DriskellHOST
Love the matchup of the DNs.
Bryan DriskellHOST
I think one of the two DNs could easily take over this game.
Bryan DriskellHOST
But I think with it also being a wet day, that also is going to factor into why the D tackles and linebackers are going to have such a big part in this.
Bryan DriskellHOST
But, yeah, this is going to be a linebacker day, in my opinion, Trev.
George MichaelsonHOST
This time, I'm talking again to Geoff Houston from APNIC Labs in his regular monthly spot on Ping.
George MichaelsonHOST
And yes, this time Geoff and I are talking about the DNS again.
George MichaelsonHOST
Continuing the exploration of the excess queries Jeff has been seeing in labs, and two questions about how the DNS operates.
George MichaelsonHOST
Firstly, what is the impact of caching and negative caching in the context of DNS queries to unique labels? Is there any way to reliably inform a resolver that the label it's asking for simply doesn't exist? that related neighbor labels cannot exist either.
George MichaelsonHOST
Would this help reduce the query burden? Secondly, Jeff has been exploring the idea of moving the DNS transport off UDP.
George MichaelsonHOST
What impact might this have on the amount of DNS query and related workload for both Resolver and the authoritative DNS server? Jeff, welcome back to Ping.
George MichaelsonHOST
What should we talk about this time? Well, George,
Geoff HustonGUEST
I can't resist.
David AndrewsHOST
And you can do it with different people, and it messes up the protection.
David AndrewsHOST
What they did this time instead of at the Super Bowl, now they drop the DNs.
David AndrewsHOST
Yep.
David AndrewsHOST
So they pack the middle, bring the middle.
PhoneboyHOST
Specifically, when HTTPS inspection blocks a TLS connection because of a server cer-- a server certificate issue, like it's revoked or expired or it's untrusted, a notification page explaining the reason for the block is actually now displayed.
PhoneboyHOST
Now, there's also a TT, uh, TTL-aware, uh, domain enforcement with DNS, which, uh, now domain objects, lookups, and caching now follow the DNS time to live value instead of fixed refresh intervals.
PhoneboyHOST
And this improves the enforcement accuracy and reduces DNS query load by approximately eighty percent.
PhoneboyHOST
Um, feature is disabled by default, though.
PhoneboyHOST
Just be aware.
PhoneboyHOST
Now, if you have a thirty-nine hundred series appliance and wonder when you can use all those ports like a switch, well, in R82.20, you can do exactly that in a manner similar to what can be done on Spark appliances, which actually run the Gaia embedded OS.
PhoneboyHOST
Now, if you use IPv6, you'll be happy to know that R82.20 provides significant enhancements in this area.
PhoneboyHOST
This includes support for IPv6 SAM rules, management over IPv6, including support for IPv6-only deployments from initial installation, uh, dead peer detection support, route-based VPNs, um, identity agent, VoIP, DNS, trap, and SD-WAN.
John HickmanHOST
We-- I wanna highlight a 15-yard run where C.J. Stroud picks up the, the first down with his, with his legs.
John HickmanHOST
The pocket on that play was amazing, and it was consistent throughout the game, where it felt like because they were able to handle the pressure, uh, fr-from how the, the Bills were able to kinda sit pressure between some of those tackle loops in with the DNs and things of that nature, or just kinda sitting five guys.
John HickmanHOST
You know, that allowed for C.J. Stroud, everything was handled correctly.
John HickmanHOST
That allowed for Stroud to climb the pocket consistently and find guys downfield or make a play with his legs.
Tom JonesHOST
If you dig down into the programming behind the web, streaming media, remote logons or any other use you can make of the internet, some modern form of Berkeley sockets lies at a low level.
Tom JonesHOST
The BSD project also made the DNS, uh, the Domain Name System a reality-
Ruben ShadeHOST
Mm
Tom JonesHOST
... that people could populate with hostnames and queries.
Brian SmithHOST
Like Louisville, they're not a great defense, but the two defensive ends are very physically gifted.
Brian SmithHOST
There's no way you're going to say they're not like SEC kind of DNs.
Brian SmithHOST
The problem is they don't have a lot of SEC secondary.
Brian SmithHOST
By the way, it's still a comedy show watching their secondary in critical moment.
Bryan C. MillsHOST
Domain names first, including the old ones bought for campaigns and never used.
Bryan C. MillsHOST
Then hosting and the DNS provider, as episode 4 will explain, is often a third company, even when you remember it is one vendor.
Bryan C. MillsHOST
Meaning that one vendor can hold your domain name, your hosting, and your DNS all in one.
Bryan C. MillsHOST
Then business email, the website platform, the email marketing service, the social profiles, analytics, and any advertising accounts attached to them.
Bryan C. MillsHOST
Then the half of the perimeter people miss, subscriptions and licenses.
Bryan C. MillsHOST
Who is your payment processor, and what name will appear on our statement? Third, let the technical records testify.
Bryan C. MillsHOST
Look up each domain on ICANN Lookup, the public registration directory run by the organization that oversees domain names, and you'll see the registrar and the registration dates.
Bryan C. MillsHOST
Run each domain through a free tool like MX Toolbox and read the DNS records as clues.
Zach Anderson-YoxsimerHOST
like having Nico makes this offense run.
Zach Anderson-YoxsimerHOST
It makes the DNs, the contained coverage, have to respect him, which is part of what makes the run game so special.
Zach Anderson-YoxsimerHOST
But he's clearly not the best quarterback, and he's not as built up as the five-star.
Zach Anderson-YoxsimerHOST
But obviously...
Ben CriddleHOST
Them prep for that.
Ben CriddleHOST
Vic Ram caught up with Braxton Lindsey, one of the best outside linebackers slash OEs slash DNs.
Ben CriddleHOST
However you look at it, at a two-point or three-point stamp, Braxton Lindsey's going to be coming off the edge and ball-in shot calling for Brigham and getting after quarterbacks.
Ben CriddleHOST
I believe that wholeheartedly.
