I've elfoip.net with bind
$ whois elfoip.net | grep 'Name Server'
Name Server: NS.ELFOIP.NET
I need elfoip.net be able to serve third levels domain, like mickymouse.elfoip.net, etc...
Yes, I'm trying to create an other useless dyndns clone.
i've added some third level as A RR.
Eg: executing this from the server itself
$ dig @localhost mattinauno.elfoip.net
;; ANSWER SECTION:
mattinauno.elfoip.net. 60 IN A 192.81.221.113
I was expecting in one or two days, from my pc i can digit in browser mattinauno.elfoip.net and get page a 192.81.221.113
But this is not happening.
Are there any prerequisites to satisfy to allow dns of my isp to be able to forward dns resolution of *.elfoip.net to MY dns ? (Or to ask to him and then cache ?)
TTL of zone is set a 5m
I've not AllowQuey
directive, is it necessary for other dns to cache from mine ?
I've cheched the zone with bind utility named-checkzone but no error detected.
How to diagnose why other dns doesn't take in account RR from mine ?
from my home pc
dig @ns.elfoip.net mattinauno.elfoip.net
