Your computer could be using numerous different DNS servers.
We’ll look at how to find which servers the computer is configured to apply and discuss a couple of circumstances where you might need to use something distinct.
To observe the DNS being utilized by Windows, work a Command Prompt and type “ipconfig /all,” accompanied by Enter. “DNS Servers” will be entered in the information disclosed.
The DNS you utilize
The most obvious way to ascertain what DNS server you’re utilizing is via Windows Command Prompt.
In Windows 10, right-tap on the Start menu and hit on Command Prompt (or Windows PowerShell — either will do). In most other variants of Windows, hit on Start, go to All Programs, later to Accessories, and ultimately on Command prompt.
Type “ipconfig /all” followed by Enter. You’ll get a lot of information.
Amid all that information, you can see “DNS Servers” listed. Typically, multiple servers store backup access if one fails to respond.
DNS Servers . . . . . . . . . . . : 2001:558:feed::1
In our case, we have several DNS servers noted: two IPv6 addresses (these with colons between the numbers – “:”) and an IPv4 address (these with periods – “.”). The first three-point to our router (a hint is that 10.1.10.1 is also the “gateway address”). The second three locations point to external DNS settings.
Yours will nearly absolutely be distinctive.
Where DNS settings originate from
Unless you revoke them, DNS settings are allocated by the ISP. When the router attaches to the internet and asks the ISP for an IP address, the response comprises the IP locations of one or more DNS servers. When your network asks the router for an IP address on the local network, the router acknowledges in one of three modes:
It moves on the DNS information the ISP gave it.
It returns its IP address, indicating the router itself will act as the DNS server.
It echoes a combination of both, as you’ve seen in the example above.
When a router serves as the DNS server, it can boost speed. Each time a DNS request is created, the router recognizes the answer. Then, when demand for the same information is made repeatedly — a regular occurrence — it can solely return the acknowledgment it already understands without requiring to stretch out to a DNS server on the web.
Suppose your computer’s DNS is fixed to the router’s IP address. In that case, most usually, a single DNS server is listed, and it’s the equivalent as the “Default Gateway” noted in the config output. Check the router’s configuration to see what DNS server you’re using for requests the router can’t fulfill. Precisely how you do depends on the router, so review the documentation that arrived with it.
Why change DNS?
In most cases, it’s pretty relevant to use the DNS servers implemented by the ISP, but you’re not expected to.
There are two purposes to estimate alternative DNS services: speed and protection.
Some public DNS servers are composed to be fast. Possibly more pragmatically, few ISP’s DNS servers aren’t intended to be fast; they’re just there because the ISP is “supposed” to implement DNS services. Switching to a diverse service can speed up the response time. If you find sheets consistently take a long time the very initial time you visit a site, or you see expressions like “resolving <domain name>” in the browser’s status bar for a long time, then try a more active DNS service might be shown.
Google’s Public DNS is one of the services.
DNS services such as OpenDNS and Quad9 (titled after their IP address: 126.96.36.199) attach security. Both blocks is identified as malicious sites. If you hold malware or are in the method of pitching for a phishing attempt, these settings can protect you by blocking or redirecting a request that would land you on a site known to be malicious. OpenDNS also has adult content and custom filtering available.
Alternative DNS servers aren’t for everybody, and they certainly aren’t needed. But if you’re encountering a DNS-related speed problem or are looking for additional protection, they might be worth investigating.
