Hi folks
With help from this list I recently updated my DNS configuration to provide
for a primary and secondary DNS server where the primary DNS server is my
host inside my domain and the secondary server is provided by AT&T
I discovered that the secondary server on file with my registrar was wrong
so I got the right data and they claim to have created a glue record but
I'm still getting that host is not responding
*primary dns ws.linuxlighthouse.com <http://ws.linuxlighthouse.com>*
*Secondary server ns2.swbell.net <http://ns2.swbell.net>*
would some kind soul direct me to a coherent glue (or duct tape) record
test?
also, given some domain name how do you know which top level domain name
servers should be the first set that you query to locate your domain in
question??
pick a random root-server: ( [a..m] means a through m )
dig @[a..m].root-servers.net. linuxlighthouse.com.
will give you the servers for com.
which are [a..m].gtld-servers.net.
dig @[a..m].gtld-servers.net. linuxlighthouse.com.
;linuxlighthouse.com. IN A
;; AUTHORITY SECTION:
linuxlighthouse.com. 172800 IN NS ns2.swbell.net.
linuxlighthouse.com. 172800 IN NS ws.linuxlighthouse.com.
;; ADDITIONAL SECTION:
ws.linuxlighthouse.com. 172800 IN A 108.220.213.121
The A record points to your primary.
If you need to find out about your IP address you use the ARPA servers
dig @[a..f].in-addr-servers.arpa. 121.213.220.108.in-addr.arpa.
will give you the servers for 108.in-addr.arpa.
dig @[ruxyz].arin.net. 121.213.220.108.in-addr.arpa.
gives you bell nameservers. Now that you are there you must search for
your PTR record.
;121.213.220.108.in-addr.arpa. IN PTR

121.213.220.108.in-addr.arpa. 7200 IN PTR ws.linuxlighthouse.com.
;; AUTHORITY SECTION:
213.220.108.in-addr.arpa. 7200 IN NS ns2.swbell.net.
213.220.108.in-addr.arpa. 7200 IN NS ns3.sbcglobal.net.
