A small blog post to me. How to dynamically update DNS zones with this shitty syntax i forget everytime ? To change a A record :
server 127.0.0.1
zone lord.re.
delete lord.re A
update add lord.re. 600 A a.b.c.d
send
Easy but so forgettable. You can put all this in a file and take nsupdate to eat it or type it interactively. To do it remotely you'll have to generate and use crypto keys. Other examples for NS
server 127.0.0.1
zone lord.re.
update add lord.re. 3600 NS zapp.lord.re
Example for SOA records
server 127.0.0.1
zone lord.re.
update add lord.re. 3600 SOA zapp.lord.re. lord.lord.re. 2015033100 3600 7200 3600 180
And voilà ;-)
