Subject: DNS TTL problem

Hello,

I am using a djbdns DNS server which operates almost perfect.

There is 1 small problem, i have for my domain frasa.net 2 namservers:

frasa.net.              3600    IN      NS      ns1.frasa.net.
frasa.net.              3600    IN      NS      ns2.frasa.net.

This is when i resolve directly on ns1.frasa.net or ns2.frasa.net

When I resolve on my ISP's nameserver and serveral others:

frasa.net.              172800  IN      NS      ns1.frasa.net.
frasa.net.              172800  IN      NS      ns2.frasa.net.

The problem is that this is a TTL of 2 days. When i Trace the dig, is see
that
the root servers are providing the 2 days TTL:

;; Received 512 bytes from 198.32.64.12#53(l.root-servers.net) in 169 ms

frasa.net.              172800  IN      NS      ns1.frasa.net.
frasa.net.              172800  IN      NS      ns2.frasa.net.
;; Received 95 bytes from 192.42.93.30#53(G.GTLD-SERVERS.net) in 154 ms

Can anyone explain this behaviour?

Cheers Mark.

Hello Mark,

This is absolutely normal... The 172800 is the parent servers
(G.GTLD-SERVERS.net) for your NS records which is default... while 3600 is
at your nameserver.

Take a look here:
http://www.dnsstuff.com/tools/dnstime.ch?name=frasa.net&type=A
http://www.dnsreport.com/tools/dnsreport.ch?domain=frasa.net

Try dnsreport.com with some other domains you will see...
