FNS2 IP change [2016-12-27]
Current benefactor (after some ownership changes) no longer wishes to serve fns2 pro bono.
I am looking for a replacement right now. Please be ready to change the fns2 IP (zones, registrars, ACLs, etc.) by the end of January 2017.
There will be further announcements with details, of course. Stay tuned.
No more NOTIFY for slave zones.
The NOTIFY has been disabled for slave zones.
If you encounter problems with it, please email me.
For automatic records update we use XML RPC; there is a simple
python script for easy IP changes.
It is enough to call the script as
freedns-dyndns.py --newaddress new.ip.add.ress
or even simpler
freedns-dyndns.py --newaddress <dynamic>
to update record to your public IP (watch for proxies!)
You may want
to fix default values in the script itself so you do not have to pass on the
params in the commandline. Old IP can be '*', no need to have it written down.
Another way is to use any dynamic dns service (like DynDNS), and have a CNAME
record pointing there.
Free DNS service for the self-reliant people who want to experiment on their
own, or keep all their zones in a single place.
We offer primary and secondary name server, automatic reloads every 15 minutes,
SRV, TXT and IPv6 support, and unique feature of web redirections / frames (see our
All zones (both primary and secondary) served by primary server
— fns1.42.pl (184.108.40.206) — are automatically replicaated to our
secondary server — fns2.42.pl (220.127.116.11 and 2001:41d0:1000:2ada::42).
If registrar needs personal info and/or zone admin email, it would be yours,
not mine. It will be you maintaining the domain, not me. Do not put me as an
admin of your domain.
If you have problems write me at
freedns at 42 pl. Please be patient — this is free service and I answer
questions when I have time.
