OpenDNS Servers : Increase internet speed using OpenDNS

Broadband is considered as high speed generating internet connection. You might have not noticed but even Broadband is not able to serve you great internet speed. This is due to downloads or heavy applications such as torrent. Do you guys know the reason behind these fluctuations in speed; it is due to DNS Servers, popularly known as Domain Name Servers. The DNS is provided by your ISP. While suing heavy files, most of us have to suffer the poor internet speed. But there is a solution to this issue. You can solve the flaw by using Public DNS servers such as OpenDNS servers.

Increase internet speed using OpenDNS
OpenDNS servers or Google DNS are public platforms that allow user to enjoy excellent Internet speed. You must know about DNS Benchmark, it is a tool that allows you to check the best channel or DNSserver IP that can help in improvising internet speed. Let us study OpenDNS Servers today
Taking a step-by-step approach, we will today discuss OpenDNS Servers and by the end of the topic, you will get to know all about Open DNS and its related concepts.
What is OpenDNS Servers?

The service of Open DNS provides network security and expands the array of DNS. It adds the features such as phishing protection and optional content filtering that help your system protect itself from malicious attacks. OpenDNS servers are available in both, free and premium packages for organizations or individuals. This helps in loading pages at much efficient speed and also blocks every channel for all kind of malicious pages. Other features that you can enjoy with OpenDNS servers are:

Domain Blocking
DNS Security
Typo Correction
Botnet Protection

OpenDNS Servers
For every individual that is using default DNS that is provided by the ISP have the provision to switch to OpenDNS server. Google DNS is also quite resourceful and you must give it a try as well. OpenDNS server IP blocks all faulty files that come along-with while downloading. Usually we see that besides using Broadband, we try hard to open a web page but it takes a while to open, this problem can be solved by using open DNS server IP. Actually Open DNS have a big pool of DNS cache that helps internet to perform better.

Consider the example:
Whenever you type any domain address in your browser such as www.bloggeroutline.com, a request is sent to the IP address of searched site and hence page opens at your system. Sometimes, due to low cache size, DNS of your site is not able to fetch the page link. This is the only reason for websites showing error and not getting displayed on request sometimes. Open DNS servers help you in overcoming such errors.
OpenDNS are considered as faster than other platforms as their servers are located at all vital locations, plus it serves larger cache size.
For individual users, OpenDNS IP is available and sufficient for routinely usage of data. You can use free packages as these are good enough for regular home users. Below mentioned is the current open DNS IP that you can use to change DNS settings:

208.67.222.222
208.67.220.220

Google DNS IP addresses
IPv4: 8.8.8.8 and/or 8.8.4.4.
IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844

How to Change DNS setting on Mac OS

Below mentioned are the steps that can help you in changing DNS settings on Mac, take a look:

Go to System Preferences
Click at Network Icon
Unlock the pane by entering password (if necessary)
Click on Advanced Button
Click at DNS Tab
Click at + button and add DNS servers
Click Apply and then OK

How to change DNS Setting in Windows Base System

By following these steps, you can change DNS settings and add new servers.
Go the Control Panel.
Click Network and Internet, then Network and Sharing Center, and click Change adapter settings.
Select the connection for which you want to configure DNS. For example: Local Area Connection or Wireless Network Connection,
right click on your choice and select Properties.
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.
Click Advanced and select the DNS tab.
Click OK.

OpenDNS servers are best suited for today’s generation as all our routinely tasks highly depends on internet. It is hence the best medium to enjoy trouble-free usage of high performance internet.

10 new features expected in Windows 10

Later this week, Microsoft is expected to reveal more details about Windows 10. But why wait for Microsoft’s announcement? Here’s what we think is coming.

New features
Later this week, Microsoft is expected to reveal more details about Windows 10. We’ve already covered some of the major new features that are in the works, such as the return of the classic Start menu UI, resizable Windows apps, the ability to launch separate instances of the desktop environment and the inclusion of Microsoft’s personal digital assistant called Cortana. But why wait for Microsoft’s announcement? Here’s what we think is coming.

PC Settings replaces Control Panel
One of the confusing things about Windows 8 for desktop users is its “PC Settings” screen, because it includes a number of settings that can also be found in the classic Control Panel. In Windows 10, more of the Control Panel settings will probably be replicated under PC Settings.

Battery Saver setting
This setting will automatically take steps to conserve the battery of your notebook or tablet when it hits a certain percentage of remaining power. We wonder if its final version will be more sophisticated than what has shown up in the Windows 10 Technical Preview versions thus far. It would make sense if it looked similar to Windows Phone 8.1’s, which shows through bars and charts the amount of power that each program uses on your device.

Customizable lock screens
Some evidence in the Windows 10 Technical Preview suggests developers may be able to make custom lock screens. This could be similar to the way lock screens can be customized in Windows Phone 8.1.

Touch targeting
Touch targeting could be implemented throughout the Windows 10 UI. The basic idea is that the design will have icons, menus, and gesture functions tuned to be more responsive for touchscreens. The UI would adjust itself automatically based on whether you are using a mouse or a touchscreen.

Continuum
This looks to be a buzzword Microsoft came up with to market Windows 10’s ability to automatically switch between its two UI modes by recognizing if you are using your device as a notebook or tablet. For example, when you attach a keyboard to a tablet, Windows 10 will switch to the desktop environment. When you remove the keyboard, the OS returns to the tile-based Modern UI.

Updated File Explorer
It’s been hinted that the Windows file manager will get an update. Most likely, the new File Explorer will incorporate touch targeting to make it more accessible for touchscreens, but we’d like to see some new functionality that would benefit its desktop OS use, too: How about allowing for multiple instances of File Explorer to be opened as tabs within the program?

New security measures
There are going to be stronger security options, including two-factor authentication where you can use a device, like a smartphone, to authorize signing into your Windows 10 user account. Also, user access tokens could be stored in a secure "container" to protect them from exposure to hackers. Other measures are aimed at the business environment: users' personal and work files kept separate from one another; and restricting employees from installing programs that haven’t been digitally signed.

New updating methods
Multiple options will give businesses more control over how they want to update their Windows 10 systems: high priority updates that brings bug fixes and security improvements; updates that add new features to Windows 10; and a third option which lets administrators schedule when they want new features to be installed on their Windows 10 systems.

New animations
Besides refreshed icon designs and background wallpaper that you expect to see in any OS release, there will be new animated effects when you interact with Windows 10, such as a window expanding or shrinking when you launch or close an application. A lingering question has been if the classic Aero theme in an updated form, or other such transparency effects, will return.

Spartan
Lastly, one of the biggies is a brand-new web browser. Appropriately named Spartan, it’s speculated that it will take design inspiration from Google’s Chrome, with emphasis on a minimal UI and performance speed. Internet Explorer will still be available in Windows 10 to ensure compatibility with sites and enterprise services that require this browser, but it looks like Microsoft wants to start moving away from IE (and its less-than-stellar reputation) and have a fresh start with the everyday user in the browser market.
