Hey everyone,
Okay, so I've been having some fun with the dig command, and wanted to dig my old school. Two questions came up from this. So I:
dig @8.8.8.8 +recurse njcu.edu ANY
and the result is about 8 records, including the SOA record. One of them is this weird TXT record, and the other is an MX and A record. The rest are auth servers which I'm assuming are DNS.
Now I know for a fact we have many subdomains..gothicnet.njcu.edu... web.njcu.edu.... etc.. why aren't those listed here? They all have IP's that are on the same IP range as the main site, njcu.edu. I can dig them individually, but why can't if I use the +recurse option see every subdomain under njcu.edu?
My other question is when I do a
dig +recurse njcu.edu ANY
This uses the DNS my ISP provides instead of google's 8.8.8.8 What I've noticed is when I do this...I only get back like half of the results, I got before, but then I also get back in the "additional Section" of the response, AAAA records which I didn't get before. And if I do this same query again immediately after, I get even less results. Why is this? Shouldn't each query give you the same exact response no matter where you get it from?
Thanks guys
