DNS : totally stumped
-
Randor, you are way smarter than me. I've never thought anything different. I just type. Most of the time things don't work. So, I just type some more. Then, sometimes I get lucky.

:laugh: :thumbsup: That's being humble! I often visualize myself stumbling, sometimes backward or sideways, but enough forward that it looks like progress. As the years pass, I stumble less! :laugh:

Anyway, You can query your DNS server and get the exact time the entry will expire. Just use nslookup and set the server to dytnohaa.metronetinc.net and query it. You want the TTL value[^].
-
That’s cool. Was using s lookup but couldn’t quite figure it out. You’re much better than RTFM! :-D
-
Roger, Your new/current hosting service has the TTL set to 86400 seconds. This is unusually high and also means that the next time your address changes you will have up to 24h downtime. I'd recommend lowering it.
-
Yep, that's a good ttl value. :thumbsup: But keep in mind that some ISP/networks will (rarely) ignore the TTL values and hold the cache for an arbitrary time regardless. Welcome to the internet, it's pure anarchy disguised as order.
Finally figured out how to get more details. Please help. Why does this show 127.0.0.53 as the Server??? nslookup > set debug > newlibre.com Server: 127.0.0.53 Address: 127.0.0.53#53 ------------ QUESTIONS: newlibre.com, type = A, class = IN ANSWERS: -> newlibre.com internet address = 64.209.142.205 ttl = 1775 AUTHORITY RECORDS: ADDITIONAL RECORDS: ------------ Non-authoritative answer: Name: newlibre.com Address: 64.209.142.205 ------------ QUESTIONS: newlibre.com, type = AAAA, class = IN ANSWERS: AUTHORITY RECORDS: ADDITIONAL RECORDS: ------------

That's the server that you are querying. On Microsoft Windows this means that you are asking the local DNS Client (Dnscache) service. The Windows Dnscache service forwards the question upstream and caches the response.

I'm completely insane so I changed the Nameservers provided by the host at my google domain set up. Previously I used customer nameservers (provided by host) and put them in at google. I deleted those & added 1 record: Host name Type TTL Data newlibre.com.newlibre.com A 1 hour 162.246.23.194 I then saved it and immediately went to nslookup on my local machine and ran it and it INSTANTLY showed up: Server: 127.0.0.53 Address: 127.0.0.53#53 Non-authoritative answer: Name: newlibre.com Address: 162.246.23.194 I'm completely insane now. Even though it now works.

Great, You can query any public DNS service by changing the target server: Try this:
nslookup
set debug
server 1.1.1.1
//Query your domain here9.9.9.9 is Quad9 8.8.8.8 is Google You can also target your router IP if it also runs a caching dns
Yep, I did that and when I targeted the new host's DNS I saw the new IP address. When I would target metronet DNS it would always give me the old one. But then when I added that A record in Google & switched to their default DNS servers then instantly my metronet DNS seemed to update & now I see the proper IP address too. I'm still stumped. But that's my natural state. :rolleyes:

You can debug this. Can you get the SOA record? The text you are pasting has "Non-authoritative answer" which means whatever DNS server you are asking doesn't own the record. Let's find the start-of-authority for your DNS zone. In your nslookup use:
set type=soa

I wonder if you two keep this thread going like this if it will travel off this monitor and onto my second monitor. sorry for the interruption, please continue.

I switched my web site to YAH (Yet Another Host) & the IP address changed, of course. I can see the new IP address from everywhere, except my home. Things I've done: I checked the DNS propagation site & the new IP address is seen around the world (DNS Propagation Checker - Global DNS Testing Tool[^]) I made the change yesterday evening & finally gave up and went to bed because I couldn't see the new ip address only from my home. Today I've: I've flushed the local dns (100 times). I've ran the release & renew ip address. Turned off local computer & all network equipment. I've turned off my Linksys wifi router for 20 minutes. I've turned off my fiber cable modem. I've backed up the wifi settings & complete restored them -- hoping to wipe the DNS cache on the wifi router -- I believe that is where this is coming from. While the router is in a rebooting state, (with the cable modem turned off) if I ping I will see the old IP address.

Ok, it's a bit confusing i know -- and i've been confused over the past few days. Originally i used smarterasp.net & they were fast but got DDOS'd a few times while I was a member and I was tired of it. I began moving to WinHost -- but then noticed they were 2x - 10x slower than smarterasp. ARgh! I have now moved newlibre.com completely to InterServer.net and they are SUPER fast & great control panel & running my .NET Core web apps with great speed. I'm very happy. If you now hit https://newlibre.com/speedTest[^] you will see the new site & the associated very fast speed.

And one more thing, I was able to get 1 month for $8 USD on InterServer.net unlimited bandwidth & unlimited diskspace. Very cheap to try out. I'm quite happy.

Has your ISP (home connection) updated their DNS servers? The DNS Propagation Checker doesn't see all the local ISPs.
Yeah, the solution was really odd. I restarted everything and did all kinds of nslookup & everything I could. Finally, I switched the DNS Servers to Google's & set an A record for my site which points to the new IP Address. The really freaky thing was that ___the instant___ after I changed that in Google's domain settings then I did a nslookup (locally) and the IP address changed in my local ISPs DNS & it started working. I'm not sure how it could've even done it that fast, but it really did.
