Domain Name System?

Your ISP controls most of what your internet operates on, including the DNS servers. Your provider automatically assigns you a couple of settings the moment you say yes to their service. DNS is where the words you enter in a browser gets translated. You see, our computers don’t use the same words as we do. When we enter a website’s name, the letters are sent to a DNS server to get shifted into digits or IP addresses. Now that’s what PCs use to communicate with each other. When they’re finally sent back to the browser, you desired page should load instantly.

Have you ever compared ISPs with your friends? Which one is better? We don’t know until we focus on the service. My ISP can be unreliable at sometimes due to sudden dropping in the internet speed.

Why Change DNS Settings on Buffalo Router?

There are a lot of reasons to change DNS settings on your router. Have you ever noticed a drop in your internet connection? You might not know this, but it’s possible that your ISP is unable to maintain a well functioning server. Anything can affect the server including getting overloaded with internet users. I don’t know about you, but I already changed my servers and I’m happy with the results. Take a look at the benefits below and what you can gain from changing DNS servers.

Enhance Your Internet Speed

One of the main reasons a certain server gets overcrowded is due to the fact that only one ISP provided internet to the country. Think about it, you are accessing the internet on the same server as anyone in the country? How overloaded can it be? Even the pages you’re used to visiting may take some time to load at this rate. To avoid such issue, you can always change your DNS server. You already know how to do so as I showed you above.

If you were lucky enough to tap into a server where you get to avoid ping time. That way, you’ll be able to browse the internet with some decent speeds. Moreover, you won’t suffer from that frustrating buffering message ever again.

Bypass Regional Restrictions

Streaming is the new entertainment methods for people who use the internet. However, streaming services have rules and no one should be able to break them. For example, every channel doesn’t allow access to viewers residing outside its region. If you live abroad, you’ll receive an error message that won’t go away unless you invest in a special service called Smart DNS ProxyThis kind of service reroutes the internet traffic that’s responsible for showcasing your current location. Once done, you can access geo-restricted channels from all around the world with ease.

It’s quite simple actually. All you have to do is follow the setup guides that are presented on any service’s website. Below you’ll find the best Smart DNS services out there. Check out their specs and choose wisely.


First, we have ExpressVPNThe number one VPN in the industry. Before we jump to the conclusion that this one is a VPN, not a DNS Proxy, you need to keep on reading. When we talk about its VPN service, this one supports protocols such as OpenVPN with TCP and UDP, SSTP, L2TP/IPsec, PPTP with 256-bit AES encryption. If you’re a security freak, you found your companion.

On the other hand, we have MediaStreamer. This is ExpressVPN’s own Smart DNS Proxy. With this, you won’t lose speed, since Smart DNS doesn’t encrypt your internet traffic. You can stream dozens of channels with MediaStreamer just by altering a few settings. They do offer a 30-day money back guarantee in case you change your mind.


BulletVPN is still new so don’t judge that fast. The service has a great server network that includes servers in 55-countries around the world.

However, we’re talking about DNS Proxy here, and this provider has an excellent one. You can always switch between Smart DNS and VPN if you’re looking for privacy. Remember, you can’t use both together.

BulletVPN offers protocols such as PPTP, L2TP, OpenVPN, IKEv1, and IKEv2. It’s a great VPN provider with a Smart DNS service. Give it a try if you want.


Another perfect option for Buffalo routers is Surfshark. With a server network of 2000+ in 65 countries, we can assume that you’ll be getting all the restricted content you’re looking for.

How Safe is Changing Your DNS Settings on Buffalo Router?

Well, the service itself doesn’t add any security value to your connection, which means it’s harmless. Smart DNS Proxy is a service for bypassing regional restrictions and that only. If you’re looking for security, you’ll need to install a VPN on your Buffalo Router.

A VPN rechannels your internet traffic through one of its servers in a chosen country. Your data will pass through an encrypted tunnel, which protects it all the way from hackers and cybercriminals. Not to mention that your IP address will be hidden as you take on a new one. This avoids any spying attempt from your ISP and even government. That said, if you truly care about staying safe and anonymous when you access the web, here are some of the top VPNs for Buffalo Routers.
