+# Using 9front as an authoritative DNS server
+
+This note describes the steps I took to make the 9front server
+at pmikkelsen.com the authoritative dns server for itself.
+
+First, I logged into my domain name registrar and changed the dns servers for
+my domain to `ns1.pmikkelsen.com` and `ns2.pmikkelsen.com` (It would not let me have
+just one, but I choose to live dangerously and point both of those domains at
+the same server). 
+
+To let the world know _where_ `ns1` and `ns2` can be found,
+I added their ip on the registrar's website (since my own dns server cannot serve
+them for good reasons). Anyways, this might not be the same for you since you
+may not use the same provider.
+
+## Starting the dns server in "serve mode"
+
+First I added 1 line to the `/cfg/$sysname/cpurc` file to enable the dns server.
+
+	ndb/dns -s
+
+After that I added a few lines in `/lib/ndb/local` to setup all the dns records I needed:
+
+	dom=pmikkelsen.com soa=
+		ip=80.240.16.196
+		mx=vps1.pmikkelsen.com pref=1
+		txtrr="v=spf1 a mx ip:80.240.16.196 ~all"
+	
+	dom=p9auth.pmikkelsen.com soa=
+		ip=80.240.16.196
+	
+	dom=vps1.pmikkelsen.com soa=
+		ip=80.240.16.196
+	
+	dom=_dmarc.pmikkelsen.com soa=
+		txtrr="v=DMARC1; p=none"
+
+With this done, I now have A records, mx records and txt records in place, so my website,
+mail and rcpu works as expected.
+
+Bye.
