Phi for All Posted October 29, 2016 Share Posted October 29, 2016 What do you mean when you say it's "undisplayed"? What happens when you type/paste www.scienceforums.net into your browser?www.scienceforums.netWhat happens when you click the link above? Link to comment Share on other sites More sharing options...
fiveworlds Posted October 29, 2016 Share Posted October 29, 2016 Sounds like a dns problem what dns servers are you using?? In windows it should be network&sharing > connection properties > Network Status > Properties > Networking > Internet Protocol Version 4 > Properties > Advanced TCP/IP settings > Dns servers in order of use Link to comment Share on other sites More sharing options...
fresh Posted October 29, 2016 Author Share Posted October 29, 2016 it means Page can not be displayed.. OS is win7. i use chrome. Link to comment Share on other sites More sharing options...
fiveworlds Posted October 29, 2016 Share Posted October 29, 2016 (edited) it means Page can not be displayed.. It is probably your default dns server though. Dns servers resolve domain names to ip addresses like a phone book. This website isn't in the phonebook you are using and therefore you can't see this site without using urlm.co. Should be the exact same for windows 7. Google's dns servers are 8.8.8.8 and 8.8.8.4. My current isp is 159.134.0.1 and 159.134.0.2 Edited October 29, 2016 by fiveworlds Link to comment Share on other sites More sharing options...

My current isp is 159.134.0.1 and 159.134.0.2 8.8.8.4 is not Google DNS server. https://groups.google.com/forum/#!topic/public-dns-discuss/shbRoNS8G1E It's 8.8.4.4 according to above thread https://developers.google.com/speed/public-dns/docs/using See Google website. BTW, Google DNS are not very fast. I have here 32 ms ping delay. Try by yourself in cmd.exe > ping 8.8.8.8 Pinging 8.8.8.8 with 32 bytes of data: Reply from 8.8.8.8: bytes=32 time=32ms TTL=45 Reply from 8.8.8.8: bytes=32 time=32ms TTL=45 Reply from 8.8.8.8: bytes=32 time=32ms TTL=45 From my ISP DNS servers I have 11 ms instead. Nearly 3 times faster response. In windows it should be network&sharing > connection properties > Network Status > Properties > Networking > Internet Protocol Version 4 > Properties > Advanced TCP/IP settings > Dns servers in order of use Faster is cmd.exe, ipconfig /all Link to comment Share on other sites More sharing options...
fiveworlds Posted October 29, 2016 Share Posted October 29, 2016 (edited) Faster is cmd.exe, ipconfig /all That doesn't set the dns server. From my ISP DNS servers I have 11 ms instead. Nearly 3 times faster response. Yes ISP should be faster however you can set your computer to lookup your ISP's dns first and if the website isn't in their list to then check google's server. You can also host your own dns and save the websites you regularly look up to your own computer like you would with phone numbers on your phone. Fresh's problem is clearly a dns problem since clicking a link on a webpage gets the dns address from that webpage. It's 8.8.4.4 according to above thread You're right I was using the following link though and just mistyped it. https://developers.google.com/speed/public-dns/ Questions like this are examinable as part of the Cisco CCNA R&S syllabus. http://www.ccna5.net/ccna-routing-and-switching-introduction-to-networks-final-exam/239 Edited October 29, 2016 by fiveworlds Link to comment Share on other sites More sharing options...

Sensei Posted November 1, 2016 Share Posted November 1, 2016 (edited) sorry, it is too technical to me, what should i do now ? That has been already said in post #3 and below: try changing DNS to different one.. On every operating system it's done different way.

StringJunky Posted November 1, 2016 Share Posted November 1, 2016 That has been already said in post #3 and below: try changing DNS to different one..

koti Posted November 2, 2016 Share Posted November 2, 2016 (edited) Click the windows icon in the bottom left corner, type in "cmd" in the search programs and files, when you see a black screen type the following: ipconfig -release (press Enter) and then: ipconfig -renew (press Enter) If it doesn't help just wait a while as the problem is most likely not on your side.

It's easy to forget to mention the little intermediate steps when you are used to doing something, especially with computers.

Or better yet, instead of all that I wrote and others wrote theres an easier way. Next time just turn everything off and on again - be sure to unplug the power cable from the router for a few seconds so it resets. Link to comment Share on other sites More sharing options...
FrankP Posted December 21, 2016 Share Posted December 21, 2016 This website functions fine for me so I will have to upvote those before me that state that it has to be something malfunctioning on your end. Hopefully you get this resolved it seems as though those above have given some pretty good resolutions. Best of luck Or better yet, instead of all that I wrote and others wrote theres an easier way. Next time just turn everything off and on again - be sure to unplug the power cable from the router for a few seconds so it resets. Haha this is funny because I was saying the other day [iT 101] = Turn it off turn it on recheck lol Link to comment Share on other sites More sharing options...
