IP Address flip-flops
I am using OpenDNS and there "Updater" at the current software level, I am running Windows 10 Pro at the April 2018 level. Modem/router is an ARRIS BGW210-700, at software level 1.5.12 , Wireless card is Intel(R) Dual Band Wireless-AC 7265, at current software level. The OPENDNS app pops up every couple of minutes. It says "Using OpenDNS Yes" . However it shows an IPADDR of 18.104.22.168 . If I click on it switches to 22.214.171.124. Sometimes it will "ping-pong" back and forth between addresses! Now when I go into Windows, IPCONFIG, it points to the modem / router address. It shows the internal IP of 192.168.1.78, which I would expect. If I connect to the modem/router control panel. it shows an IPADDR of 107.219.183.**, which is the same address that is shown when I log on to the OPENDNS (Umbrella) dashboard. I am running Windows 10 Pro Version 1803 (Build 17134.81) which is the current production built with all updates applied. When I use reverse lookup on 107.219.183.** the address shows as 107-219-183-**.lightspeed.cntmoh.sbcglobal.net, which is what I would expect. However, reverse lookup on 104.239.207,44 shows it is a RACKSPACE address. And reverse lookup on 126.96.36.199 shows as a Search Guide Inc IPADDR, Is this normal? What is going on? I initially posted the above to OPENDNS/CISCO support and they came back with: ".... It sounds like ATT might be using a proxy or these 2 addresses could be in ATT's pool. I recommend you reach out to your ISP to inquire about this behaviour as this is not something done by OpenDNS." ** added above to mask ipaddr ...
