    Shot in the dark: hosts file? Try from a different device, like a phone on wifi.

    Software rusts. Simon Stephenson, ca 1994. So does this signature. me, 2012

    Thanks for the ideas. I have tried from other devices also. I just powered everything down & disconnected power plugs & then restarted everything. My phone goes to cell network when wifi is down & when I ping from phone I see new IP address. As soon as the wifi comes up & cell reconnects to it then I get the old ip address. I'm insane now. :rolleyes:

      I recently shipped a laptop to a new wfh hire. Many of the websites that we use for support were failing due to DNS. It turned out to be a setting in the WiFi router that was set to use the ISP's DNS service. I turned that off and manually set it to use Google's dns and everything was fine.

      That's my final idea. That the DNS from my ISP is not updated. It's metronet and I believe the DNS is dytnohaa.metronetinc.net (shows up in DHCP on router). But I don't see anyway to change that. :(

        Geez, I see why your old host was slow as molasses, they have 71 domains on your old VPS box. Sometimes wonder how you guys that write books put your shoes on in the morning. Probably need a manual. :rose:

        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.

          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.

                        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 here

                            9.9.9.9 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 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.

                                      ping newlibre.com
                                      PING newlibre.com (64.209.142.205) 56(84) bytes of data.
                                      From RADNet (192.168.5.1) icmp_seq=17 Destination Net Unreachable

                                      At one point the router is completely down & I see:

                                      $ ping newlibre.com
                                      ping: newlibre.com: Temporary failure in name resolution

                                      That I was thinking would be good. Finally, everything comes back and again I ping the site & get the old 64.209.142.205 address. Also, if you check the DNS that everyone sees it is the new one: DNS Propagation Checker - Global DNS Testing Tool[^] This is insanity! I can get to the new site from my work computer when I VPN to it & go to browser. It's only here in my home that I cannot get to it. Insanity.

                                        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.
