• Summer fun with a DNS resolver

    On my way back home from the IETF93 meeting in Prague I decided to do a small summer project. For a long time I have wanted to run my own DNS resolver. Lately I had considered to run it on my Synology NAS. But my NAS is already stretched by all the applications running. So I decided to use one of my Raspberry Pi's to do the job. Now, after some runs of the washing machine, I am ready to go.

  • Packet size and name server authorative zone

    As preparation for the changing of keys used in the .se zone I have done some tests about packet sizes with different key sizes and algorithms. Currently the .se zone is signed by a 2048 bit Key Signing Key (KSK) and a 1024 bit Zone Signing Key (ZSK) both in RSA-SHA1 format.
