🌐 What Is My DNS Server
Find the DNS resolver your connection is actually using, not the one in your settings. See the resolver address, the operator behind it and its country, then compare it against your own connection to spot a foreign resolver or a DNS leak.
This page looks up the DNS resolver your browser is really using, not the one in your settings. It shows the resolver address, the network that runs it and country, then compares it against your own connection. Nothing is guessed: the resolver is identified by the lookup itself.

Why Your DNS Resolver Matters In Bangladesh
Bangladesh sits far from most public DNS infrastructure. A query to a resolver in another country crosses international links twice, so every new domain you open starts with that extra round trip. On a good line it is tens of milliseconds; on a congested evening it is more, and it lands on the slowest part of any page load, before the first byte arrives.
More importantly, the resolver decides where local content comes from. It is the vantage point the internet sees for you, so it decides which copy of a mirrored site you get. A resolver inside Bangladesh usually returns a Bangladeshi address, including content mirrored on servers inside the BDIX community. A resolver abroad often returns the overseas copy instead, so a request that could have been served over the local exchange leaves the country and comes back.
That is why "faster DNS" is not the same as "a faster resolver". For most Bangladeshi connections the ISP resolver is the cheapest hop and the one closest to BDIX, but it is also the resolver your ISP can log, filter or redirect. A public resolver such as Cloudflare or Quad9 buys you privacy and filtering, at the cost of a longer first-lookup and possibly a foreign copy of local content. Neither choice is wrong; they optimise different things.
If you use a VPN, the resolver should be the VPN provider's. If this page names your ISP instead while the VPN is connected, lookups are escaping outside the tunnel, which is the DNS leak described in the FAQ below.
Public DNS Resolvers Compared
If you decide to switch, these are the resolvers people actually use in Bangladesh. All support plain DNS and DNS over HTTPS.
| Provider | IPv4 | IPv6 | Filtering | Notes |
|---|---|---|---|---|
| Cloudflare 1.1.1.1 | 1.1.1.1 / 1.0.0.1 | 2606:4700:4700::1111 | No | Fastest global anycast. No filtering, logs dropped daily. Very common as a browser default. |
| Google Public DNS | 8.8.8.8 / 8.8.4.4 | 2001:4860:4860::8888 | No | Very reliable. Keeps anonymised logs for a short period. |
| Quad9 | 9.9.9.9 / 149.112.112.112 | 2620:fe::fe | Malware | Blocks known malware domains by default. Good default for families. |
| AdGuard DNS | 94.140.14.14 / 94.140.15.15 | 2a10:50c0::ad1:ff | Ads and trackers | Blocks ads and trackers at the DNS layer. Can break sites that share ad domains. |
| OpenDNS | 208.67.222.222 / 208.67.220.220 | 2620:119:35::35 | Optional | Long-running service with parental-control and phishing options. |
Some routers and browsers only accept one pair of addresses, so keep both for the same provider. Mixing providers can send lookups unpredictably.
How To Check And Change Your DNS Server
Check Which Resolver Answers
An echo record reports the resolver that handled the query, so it works even when the settings are misleading.
| System | Command |
|---|---|
| Windows (Command Prompt) | nslookup -type=txt o-o.myaddr.l.google.com |
| macOS / Linux | dig +short TXT o-o.myaddr.l.google.com |
| Windows current settings | ipconfig /all |
| macOS current settings | scutil --dns |
| Linux current settings | resolvectl status |
When those two disagree, something between your device and the internet is rewriting DNS: usually the router, an ISP redirect, or browser secure DNS. The echo record is the truthful one.
Change It
- Windows: Settings → Network & Internet → your adapter → DNS server assignment. Change it per adapter.
- macOS: System Settings → Network → your connection → Details → DNS. Add the addresses and remove the old ones.
- Android: Private DNS is the modern option and accepts a hostname such as cloudflare-dns.com. Older Android only allows per-Wi-Fi settings.
- iPhone and iPad: DNS is set per Wi-Fi network under Configure DNS, or globally with a DNS profile.
- Router: change it in the WAN or DHCP settings. This covers every device on the network at once, and is the fastest way to fix a home connection.
Browser secure DNS beats all of the above. If a change seems to have no effect, check the secure DNS or DNS over HTTPS setting in your browser first.
FAQ (Frequently Asked Questions)
What is my DNS server?
Your DNS server, or resolver, is the machine that turns a name like example.com into the IP address your browser connects to. This page shows the resolver your lookup actually travelled through, plus the network that runs it.
How can I check my DNS server without a browser?
Use an echo record. On Windows run nslookup -type=txt o-o.myaddr.l.google.com; on macOS or Linux run dig +short TXT o-o.myaddr.l.google.com. The answer is the address of the resolver that handled the query, not your own address.
Should I use my ISP DNS or a public one like 1.1.1.1?
It is a trade-off, not a clear win. Your ISP resolver is normally the closest one to you, so names resolve in a few milliseconds and Bangladeshi sites, BDIX-hosted servers and local CDN copies resolve to local addresses. A public resolver such as 1.1.1.1 or 8.8.8.8 is often outside Bangladesh, so lookups cost more round trips and some content can be resolved to a foreign copy. Public resolvers usually do better on privacy and filtering, and are worth it on a network that hijacks or blocks DNS.
Does changing my DNS server make my internet faster?
It changes lookup time, not bandwidth. Every new domain needs a lookup before the first byte is sent, so a resolver with high latency adds a delay to the start of each connection. Once the connection is open, speed depends on your line, not your resolver. A nearby resolver feels faster on page loads; it will not raise a speed test result.
Why does this page show a different DNS server than my router or settings?
Two common reasons. First, browser secure DNS (DNS over HTTPS) overrides the DNS servers set in your operating system, so Chrome, Edge or Firefox can send lookups to their own resolver while your router still shows the ISP address. Second, routers and VPN clients often forward or intercept port 53 traffic, so the address in your settings is not the one answering. A VPN, if it is on, replaces the resolver entirely.
What is a DNS leak?
A DNS leak is when your lookups still go to your ISP resolver while you believe a VPN is handling them. The traffic is encrypted but the names you visit are visible to the ISP. The comparison on this page is the quick check: if the resolver is operated by your ISP or by a network in your own country while a VPN is active, lookups are probably leaking. A properly configured VPN shows its own resolver instead.
Is this DNS check private?
Mostly. Detection needs one request to a third-party DNS echo service, so that service sees your IP and the address of your resolver, and it returns only the resolver address. The resolver address is then enriched on our server over plain DNS. We do not store it against you. If you would rather not make that request, the manual commands above work entirely on your own machine.
Why is my resolver in another country?
Three usual causes: you are on a public resolver with no server in Bangladesh, you are on a VPN, or your ISP forwards lookups to a foreign upstream. It matters because a foreign resolver sees an overseas vantage point, so it can hand you a CDN copy or a locale meant for another country, which is slower and can change prices or availability on some sites.
