Unable to access my web site from the Internet or ISP?

Sometimes you may not be able to access web site from your computer internet but site just works fine from another ISP or location.

Here are the possible reasons:

1) Your Internet DNS servers not resolving your web site properly.

2) Your computer might be having browsing cache problems.

3) Your Internet IP blocked with web hosting provider for various reasons.

 

1. Your Internet DNS servers not resolving your web site properly.

 Find out if your ISP is having DNS problems.

Your ISP could be the source of the problem. One possibility is that one of its DNS servers is down and you're trying to access the downed server.
If you know the addresses of the DNS servers, ping each of your ISP's DNS servers, and if any of them don't respond, remove them from your DNS list.

 You can use any FREE Public DNS servers for testing. We suggest you to use Google Public DNS.

 Google Public DNS is a free, global Domain Name System (DNS) resolution service, that you can use as an alternative to your current DNS provider.

 To try it out:

 Configure your network settings to use the IP addresses 8.8.8.8 and 8.8.4.4  as your DNS servers.

 Once you configure your web browser/client programs will perform all DNS lookups using Google Public DNS instead of your ISP.

 

Changing your DNS servers settings

 Because the instructions differ between different versions/releases of each operating system, we only give one version as an example.

 Note: Depending on your network setup, you may need administrator/root privileges to change these settings.

Microsoft Windows

DNS settings are specified in the TCP/IP Properties window for the selected network connection. 

Example: Changing DNS server settings on Microsoft Windows 7

  1. Go the Control Panel.
  2. Click Network and Internet, then Network and Sharing Center, and click Change adapter settings.
  3. Select the connection for which you want to configure Google Public DNS. For example:
    • To change the settings for an Ethernet connection, right-click Local Area Connection, and click Properties.
    • To change the settings for a wireless connection, right-click Wireless Network Connection, and click Properties.
    If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  4. Select the Networking tab. Under This connection uses the following items, select Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6) and then click Properties.
  5. Click Advanced and select the DNS tab. If there are any DNS server IP addresses listed there, write them down for future reference, and remove them from this window.
  6. Click OK.
  7. Select Use the following DNS server addresses. If there are any IP addresses listed in the Preferred DNS server or Alternate DNS server, write them down for future reference.
  8. Replace those addresses with the IP addresses of the Google DNS servers:
    • For IPv4: 8.8.8.8 and/or 8.8.4.4.
    • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844
  9. Restart the connection you selected in step 3.

   10. Test that your setup is working correctly;

Mac OS X

DNS settings are specified in the Network window. 

Example: Changing DNS server settings on Mac OS 10.5

  1. From the Apple menu, click System Preferences, then click Network
  2. If the lock icon in the lower left-hand corner of the window is locked, click the icon to make changes, and when prompted to authenticate, enter your password.
  3. Select the connection for which you want to configure Google Public DNS. For example:
    • To change the settings for an Ethernet connection, select Built-In Ethernet, and click Advanced.
    • To change the settings for a wireless connection, select Airport, and click Advanced.
  4. Select the DNS tab.
  5. Click + to replace any listed addresses with, or add, the Google IP addresses at the top of the list:
    • For IPv4: 8.8.8.8 and/or 8.8.4.4.
    • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844
  6. Click Apply and OK.
  7. Test that your setup is working correctly;

To test that the Google DNS resolver is working:

From your browser, type in a hostname, such as http://www.google.com. If it resolves correctly everything is working correctly.

 

Switching back to your old DNS settings

If you had not previously configured any customized DNS servers, to switch back to your old settings, in the window in which you specified the Google IP addresses, select the option to enable obtaining DNS server addresses automatically, and/or delete the Google IP addresses. This will revert your settings to using your ISP's default servers.

If you need to manually specify any addresses, use the procedures above to specify the old IP addresses.

If necessary, restart your system.

 

2. Your computer might be having browsing cache problems.

If you've found yourself hitting DNS errors or 404 pages in your browser but you know your net connection is working fine, it might be time to flush and restart Windows' DNS cache. After launching a command prompt as an administrator and closing down IE/Firefox (which has its own DNS cache), enter the following

> ipconfig /flushdns
> net stop dnscache
> net start dnscache

Restart browser and try accessing web site you like.

 

3. Your Internet IP blocked with web hosting provider for various reasons.

If the above two solutions are not bringing your web site, please open helpdesk ticket or live chat with our staff to check your IP blocks if any.

Submit your IP address while opening Helpdesk ticket/Live chat. To know your IP address go to http://www.ipchicken.com

Note: We never block public IP address unless some attact from that IP or many login failures ( Brute Force attack).
