Recently changed your DNS records, switched web host, or started a new website: then you are at the right place! DNSChecker provides a FREE DNS lookup service to check Domain Name System records against a selected list of DNS servers located in multiple regions worldwide.
Perform a quick DNS propagation lookup for any hostname, and check DNS data collected from all available DNS Servers to confirm that the DNS records are fully propagated.
Global DNS Checker
The tool is a quick and easy way to do a DNS lookup to check DNS propagation and view information for each domain from DNS servers in many countries.
You can test whether changes to new or existing domains have been updated correctly without having to do remote inquiries manually. This gives you an instant insight into how users around the world may be resolving DNS records for your website, email, or other online service.
What is DNS and how does it work?
The Internet is a huge computer network. Every device connected to the Internet is assigned a unique IP address to help other computers identify it. This IP address is a series of numbers with periods, as shown below: 184.108.40.206
Now imagine if you have to remember such a long string of numbers to visit your favorite website. If you enter them in your browser, they are difficult to remember and will not tell you any information about the website you will see.
Domain names were invented to solve this problem by using letters and allowing users to choose easy-to-remember names for their websites.
DNS or domain name systems basically convert these domain names into IP addresses and point your device in the right direction.
The domain name and its matching IP address are called “DNS records”.
Here is a simple way to understand how DNS works in four steps.
1. You open a browser and type www.DNSChecker.cyou in the address bar, and then press Enter on the keyboard. Quickly check immediately whether you have visited our website before. If the DNS record is found in your computer’s DNS cache, the rest of the DNS lookup will be skipped and you will be taken directly to www.DNSChecker.cyou
2. If the DNS record is not found, a query will be sent to your local DNS server. Usually, this is your Internet provider’s server, which is commonly referred to as a “resolving name server”.
3. If the record is not cached on the resolving domain name server, the request is forwarded to the so-called “root domain name server” to locate the DNS record. The root domain name server is a designated server all over the world, responsible for storing DNS data and keeping the system running normally. Once the DNS record is found on the root name server, it will be cached by your computer.
4. Now that the DNS record is found, a connection to the server storing the website will be opened, and www.DNSChecker.cyou will be displayed on your screen.
What is DNS Propagation?
DNS propagation is the term commonly used to check the current state of results globally. This process can take only a few minutes or up to 48 hours or longer.
Technically DNS does not propagate, but this is the term that people have become familiar with. Requests are forwarded from the locally used resolver to the authoritative nameserver on demand then cached to speed up future DNS lookups.
For popular websites, results may be cached for people in different parts of the world. If you have recently made changes to your configuration, this may mean that some people will be receiving old results until the TTL expires.
Which DNS records can be checked?
You can perform checks for common record types including:
- A – The most common type, used to point to an IP address.
- CNAME – Canonical name or alias, they point to other records.
- MX – Mail Exchanger, these are used to set email servers and their priority.
- NS – Nameserver, these store the authoritative nameserver.
- TXT – Text, commonly used for configuration settings.
Additional types that can be checked which are usually used in more advanced configurations include: AAAA, CAA, PTR, SOA and SRV.
