You know you can improve both the performance of your Internet browsing and security by choosing alternative DNS; The good news is that it is free and you'll need about one minute of your time to switch to another provider.
What is a DNS resolver?
The Domain Names System (DΝS) είναι γνωστά σε αυτούς που ασχολούνται με το Internet, αλλά ένας μέσος ή αρχάριος user he probably doesn't know or care what DNS is, or what it can do.
DNS connects domain names and IP addresses. If you own a server and want to allow connection to it, it is best to use a name. It's easy to remember, or rather easier than an IP address number. There are several online services that sell domain names. Once you buy a domain, you should associate it with your server's IP address, and then anyone interested can access it, your domain name, instead of having to type in the IP address.
A DNS resolver server allows a computer (or user) to search for a domain name (such as iguru.gr) and find the IP address of the server hosting the website. Think of the DNS resolver server as a computer directory.
So when you type the domain name of a web page in your web browser behind the scenes, there is the DNS resolver server, which will turn your computer to the correct IP address by analyzing the domain name in numbers. So your browser will discover the webpage you typed.
Which DNS resolver are set up for you?
Most users at home use the DNS resolver of the Internet Service Provider (ISP), or to put it in Greek, the Internet service provider. They are usually used automatically when you set up your router. You can find out which DNS resolver you are using by going to your router's settings page, through the "WAN" tab. There look in the "DNS Servers" section. Usually there are two, one principal and one alternate. These DNS servers may or may not be hosted by your ISP.
You can also see it DNS server που χρησιμοποιείται στον υπολογιστή σας ανοίγοντας ένα παράθυρο γραμμής εντολών και πληκτρολογώντας την εντολή “nslookup” και μετά enter. Θα δείτε το “Default DΝS Server” και τη διεύθυνση IP.
Why would I want to use an alternate DNS Resolver from the one my ISP gives me?
Your ISP may have done a good job with the DNS Resolver servers, and can be completely secure. But it may not be. Their servers can have endless pores and awesome hardware, offering you super fast response times. But it may not.
You may want to use an alternative for three main reasons:
1. Alternative DNS resolvers can give you very fast web browsing
Some alternative DNS providers claim to use DNS public servers to provide a faster browsing experience for end users with a noticeable reduction in the delay for DNS searches. Of course, to observe it, you should have the relevant experience, but you probably know when a connection is slow. You can try and if it seems slow, you can always go back to your old ISP by changing DNS whenever you want.
2. Alternatives to DNS Resolvers improve security while browsing
Some alternative DNS providers claim that the solutions they offer improve security by filtering out malware, phishing, and phishing or malicious sites. This reduces the risk of attacks DNS cache poisoning.
3. Some Alternative Reselvers DNS Providers offer automatic content filtering
Do you want to try adding filters for your children so they do not have access to porn sites, or other "non-family" websites? You can select a DNS provider that filters the content. The service Norton ConnectSafe DNS servers offers DNS resolution servers filtering inappropriate content. This does not mean that your children cannot simply type in the IP address of an inappropriate website and gain access to it. But then we are not talking about children but "hackers."
How do you change your DNS Resolver with an alternative DNS provider?
The best way to change DNS providers is from your router. This will change them from one place only. Once you change DNS Resolvers to your router, all your network applications will use the new DNS servers automatically.
Check your router's manual for how and where to change the DNS records. There are usually two to three locations to enter DNS Server IP addresses.
Before making any changes, write some of the current settings in case your changes do not work.
