Below are the DNS servers that I have been using for many years:
18.104.22.168 DNS Watch (Hostname: resolver1.ihgip.net ISP: Accelerated IT Services GmbH) 22.214.171.124 Uncensored DNS (IP: 126.96.36.199 Hostname: deic-lgb.anycast.censurfridns.dk ISP: Danmarks Tekniske Universitet) 188.8.131.52 Foebud (Hostname: h1768020.stratoserver.net ISP: Strato AG) 184.108.40.206 OpenNIC (DE) (Hostname: quaternary.server.edv-froehlich.de ISP: KAMP Netzwerkdienste GmbH) 220.127.116.11 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
18.104.22.168 Google 22.214.171.124 Google 126.96.36.199 OpenDNS 188.8.131.52 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: 184.108.40.206 Name: pressreader.com Address: 220.127.116.11 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 ip4:18.104.22.168 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 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 = 126.96.36.199
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 188.8.131.52 into my browser and clicked Go. Below is the response:
184.108.40.206 - 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.
