Below are the DNS servers that I have been using for many years:
22.214.171.124 DNS Watch (Hostname: resolver1.ihgip.net ISP: Accelerated IT Services GmbH) 126.96.36.199 Uncensored DNS (IP: 188.8.131.52 Hostname: deic-lgb.anycast.censurfridns.dk ISP: Danmarks Tekniske Universitet) 184.108.40.206 Foebud (Hostname: h1768020.stratoserver.net ISP: Strato AG) 220.127.116.11 OpenNIC (DE) (Hostname: quaternary.server.edv-froehlich.de ISP: KAMP Netzwerkdienste GmbH) 18.104.22.168 OpenNIC (NL) (Hostname: none ISP: Digital Ocean)
I used to be able to access the website pressreader.com in the past until recently. About a month ago, if I typed www.pressreader.com directly into my browser, the website would be inaccessible. (Note: I have no problem accessing other websites at all.)
I now use one of the workarounds below:
a. launch a search engine like Google or DuckDuckGo b. type "pressreader climate change" (without quotes) or any phrase that includes pressreader as one of the words c. from the list of the results of the search, click on any result that has the word Pressreader
Use a VPN (free or paid service) to access Pressreader
Change my existing DNS servers to either Google's, OpenDNS' or those provided by my ISP
22.214.171.124 Google 126.96.36.199 Google 188.8.131.52 OpenDNS 184.108.40.206 OpenDNS
I only read news on pressreader.com at home. My home computer is connected to the modem (provided by my ISP).
Am I right to believe that the DNS servers that I have been using all this while have been poisoned?
Per Moonsik Park's suggestion
I typed nslookup -query=any pressreader.com in a terminal/console and below are the results:
username@hostname:~$ nslookup -query=any pressreader.com ;; Truncated, retrying in TCP mode. Non-authoritative answer: Name: pressreader.com Address: 220.127.116.11 Name: pressreader.com Address: 18.104.22.168 pressreader.com nameserver = ns2.newspaperdirect.com. pressreader.com nameserver = ns3.newspaperdirect.com. pressreader.com origin = ns2.newspaperdirect.com mail addr = hostmaster1.newspaperdirect.com serial = 1018 refresh = 900 retry = 600 expire = 86400 minimum = 3600 pressreader.com mail exchanger = 20 ndmail.newspaperdirect.com. pressreader.com mail exchanger = 10 adab.pressreader.com. pressreader.com text = "ZA=4CgDvbUCl3GAgI0vDd2dKw==" pressreader.com text = "globalsign-domain-verification=EDgZxi7787wPfMQiYBv6Ozzb_TN1aizyNzGX4ivO98" pressreader.com text = "_globalsign-domain-verification=wFqJgfjXebcCp5uT9zGMgShVZ2CoKeUUW-oyud5cO1" pressreader.com text = "globalsign-domain-verification=3c-6TB-cG8LBvkfkOGKMCjIEzTjuPaL-U1mJ_PjnNe" pressreader.com text = "MS=A8AD5E10FE533C17EDA5293095360D727A967AAA" pressreader.com text = "cloudflare-verify 189356383-34794676" pressreader.com text = "v=spf1 mx ip4:22.214.171.124 ip4:126.96.36.199 ip4:188.8.131.52 ip4:184.108.40.206 ip4:220.127.116.11 ip4:18.104.22.168 ip4:22.214.171.124 ip4:126.96.36.199 include:sendgrid.net include:mail.zendesk.com include:servers.mcsv.net -all" pressreader.com text = "MS=ms36475603" pressreader.com text = "globalsign-domain-verification=AtQ1zLCdH6JdJ_bs3f2aP9sBShOfzhFCCTJ8tfwk9j" Authoritative answers can be found from: adab.pressreader.com internet address = 188.8.131.52
Next, I accessed www.centralops.net/co and typed pressreader.com. The results provided the same details as those obtained by performing a local nslookup query.
Finally I typed 184.108.40.206 into my browser and clicked Go. Below is the response:
220.127.116.11 - Resolving failed Error code 22 The proxy failed to resolve site from host name, if this site was recently added please allow a few minutes before trying again.
