DNS SRTT and how it works

Hey everyone, it seems to be a back and forth conversation about how SRTT works and does it apply to Caching servers or Forwarders as well. My understanding is that the SRTT algorithm uses multiple variables to determine the best authoritative server to query. Some also say Forwarding uses the same algorithm, but I thought it just used RTT (Round-Robin).

Let me know what you guys think

nslookup gives nonsense (to me) results – help!

I’m just starting to learn the material for an A+ certification (a Mike Meyers course), and I go to my (Win 10) console and type in nslookup, I get the following:

C:WINDOWSsystem32>nslookup DNS request timed out. timeout was 2 seconds. Default Server: UnKnown Address: 2000::ff 

likewise, ipconfig /all gives me

DNS Servers . . . . . . . . . . . : 2000::ff 2000::fe 192.168.1.1 

2000:0000:0000:0000:ff isn’t even a legit IPv6 address is it?

My network properties are set to automatically find a DNS server (from Spectrum, I assume)

And my browser continues to find any website I type into it. So what’s going on?

Would hate to just skip the DNS lesson and continue on without knowing the problem.

Does DANE support “classical signed” certificates?

Hi, let’s suppose i have a classical certificate (not from letsencrypt) because of $reasons. can i use it in DANE? As it is stored and retrievable for recognition/validation/testing from DNS(SEC)? Does DANE even support SANs (Subject Alternative Names) in these certificates?

if so, which server software does support that usecase? google didn’t help me very much

what fqdn for shared DNS servers

I am building 2 internet facing DNS servers that will host DNS records for many domains. What should the domain be for the DNS servers? the nameservers will be named something generic like ns1 and ns2, just not sure about which domain they should be part of. should i pick the first zone I add and make that domain the one the DNS servers are part of? create a new domain for DNS?! that would kinda be a waste.
