List all ALiases of A Records!

[Hugo]

Hi! All,

Our Domain DNS server is not under my control. I have to inform my main I.T
for any DNS requirements, which obviously take a lot of time. I hope I can
get what I want by querying my DNS server.

My requirement as of now is to get a list of all DNS Aliases for my A
records.

Ex:My domain: par.edu.us.org

C:\NSLOOKUP
> ls -a par.edu.us.org

I guess I am getting ony the first CNAME of all servers. I know I have more
than 1 Alias for my A records.

How can I list out all the Aliases for a domain or a A records?

Thanks a lot

Unfortunately, if you send such a command, the DNS server thinks it's a zone
transfer request (since you are trying to get multiple records), and you
will get an error such as the following (which I got when I tried the
query):

*** Can't list domain par.edu.us.org: Non-existent domain
The DNS server refused to transfer the zone par.edu.us.org to your computer.
If thisis incorrect, check the zone transfer security settings for
par.edu.us.org on the DNS
server at IP address

I do not believe your IT department will provide you with the ability to
receive a zone transfer. But then again, no hurt in asking them.

If you need a complete list of records, and you do not have direct access to
the DNS servers, your best bet is to ask your IT department for a complete
enumeration of all records for your zone. This way you can evaluate the
records and make decisions on changing/updating them as a whole.
