Hi Bjørn Never realised of such compression on answered. Is this is something well documented? Curious. Thanks for sharing. On Wed, Apr 4, 2018 at 1:30 AM, Bjørn Mork <bjorn@mork.no> wrote:
At first I thought they had disabled compression:
bjorn@miraculix:~$ dig . ns @1.1.1.1|grep SIZE ;; MSG SIZE rcvd: 431 bjorn@miraculix:~$ dig . ns @8.8.8.8|grep SIZE ;; MSG SIZE rcvd: 239 bjorn@miraculix:~$ dig . ns @9.9.9.9|grep SIZE ;; MSG SIZE rcvd: 239
But then I noticed that they *do* compress other names:
bjorn@miraculix:~$ dig net ns @1.1.1.1|grep SIZE ;; MSG SIZE rcvd: 253 bjorn@miraculix:~$ dig net ns @8.8.8.8|grep SIZE ;; MSG SIZE rcvd: 253 bjorn@miraculix:~$ dig net ns @9.9.9.9|grep SIZE ;; MSG SIZE rcvd: 253
Which just makes it even more confusing. What's so special about root? Except for the obvious :-)
