DNS Lookup - Check DNS records for any domain
What is DNS Lookup?
A DNS lookup usually refers to the process of translating an easy-to-remember name called a domain name (such as www.google.com) into a number called an IP address (such as 192.168.2.1). Via DNS lookup tools DNS stands for Domain Name System. The system is responsible for translating host names (dnschecker.org) into suitable IP addresses for your computer.
When an end-user types a domain or URL into their browser's search bar, a DNS server processes the request and translates it to the corresponding IP address so that the browser can load the relevant results.
Computers use these numbers to communicate with each other on the Internet, but these numbers are difficult for humans to remember and may change from time to time if network configurations require changes. You can think of DNS lookups as similar to your phone's contact list, but with a special one that includes all names without giving out your phone number and automatically updates your phone when it gets a new number. is. You don't have to remember every contact's number, but you can quickly and easily look up a contact's name. When you select a name and make a call, your phone automatically uses your current phone number.
How does a DNS lookup work?
The Domain Name System( DNS) is a series of waiters located each around the world that store the configuration information of a sphere name in order to make the process of converting a sphere name into an IP address or other DNS configuration information to more fluently pierce a garçon.
There are 4 different types of DNS waiters involved when performing a DNS lookup. Each DNS garçon type has a different part to play and may not each be needed under certain circumstances.
Recursive determinedness is the DNS garçon that your computer or device communicates with. This DNS garçon is generally issued to you automatically by your service provider and is geographically located hard in order to return results as fast as possible. This garçon will cache DNS record data in order to speed up unborn DNS lookup requests.
Root Nameserver- The root name garçon is responsible for returning the IP address of the TLD nameserver. For illustration, when resolvingexample.com, the root name garçon will return the IP address of the TLD name garçon responsible for. com sphere names.
TLD Nameserver The Top Level Domain( TLD) name garçon is responsible for returning the authoritative name waiters for all disciplines under the TLD it's responsible for. The. com TLD name garçon will return results forexample.com but notexample.org.
Authoritative Nameserver This is the DNS garçon for actually storing the DNS configuration data of a sphere name. For illustration, DNS lookup inflow
As an illustration of the inflow of events when performing a DNS lookup, this is the order of events that will be when you request a URL to visit a website likeexample.com in your web cybersurfer.
Why are DNS records cached?
When DNS requests are made, the response includes what's known as the Time to Live( TTL), which specifies the number of seconds in which DNS records should be cached for.
Caching Generally happens at the recursive determinedness being used, as these are generally used by numerous druggies on a network with close geographical distance. This won't only speed up posterior requests for the stoner who made the original request but all other druggies using the same DNS determinedness. Caching DNS records can make a big difference to response times as frequently numerous authoritative nameservers are located on the other side of the world for transnational druggies and if your web cybersurfer can skip corridor of the full DNS lookup process and just get the IP address of a sphere name from a original cache also the request can be sped up significantly.
What's a rear DNS lookup?
A rear DNS lookup is the contrary of a regular DNS lookup. rather of converting a sphere name into an IP address, it converts an IP address into a sphere name. The DNS garçon will need to have a PTR record pointing to the sphere name.
How do you do a DNS lookup?
Utmost of the time, a DNS lookup is commodity that you don't need to worry about, as your operating system, or web cybersurfer, will handle this for you automatically when you need to resolve a sphere name. numerous operating systems include a DNS lookup tool for performing DNS lookups manually for diagnosing problems. Windows systems give a command line tool called nslookup, and Linux and Mac systems include the important dig tool.
Using these command line tools can be complicated and delicate to understand fornon-technical people, which is why the whatsmydns DNS lookup tool was created to help with snappily performing a DNS check.
As an online volition, all you need to do is simply enter the sphere name that you want to perform a DNS lookup against, and the results will be displayed right in your web cybersurfer. This provides indeed neophyte druggies with an easy- to- use DNS lookup tool.
For added convenience, a devoted Google Chrome DNS Lookup extension has been created to snappily see DNS records for the website you are presently on.
What types of DNS records can be searched?
There are different types of DNS records used for different purposes. For example, the domain name www.example.com can host websites (A records), send and receive email (MX records), and use VoIP (SRV records). A different DNS record type is used to configure each of these services. You can use the DNS lookup tool to perform DNS lookups for any domain name for the following record types: Record Lookup – Address or IPv4 DNS record. These store the IP address of the domain name. One record: The simplest type of record, also called address record, provides her IPv4 address for a domain name or subdomain name. This record references a domain name to an IP address.
AAAA Record Lookup - Addresses a v6 or IPv6 DNS record like an A record, but saves an IPv6 IP address. AAAA records: Map host names to 128-bit IPv6 addresses. For a long time, machines on the Internet were identified using 32-bit IPv4 addresses. However, because IPv4 does not exist, IPv6 was developed. The four "A's" (AAAA) are a mnemonic for IPv6, which is four times larger than IPv4.
CAA Record Lookup - CA Authorization DNS records are used to store which CAs are authorized to issue certificates for a domain. CAA record: Also known as a certification authority authorization record, it reflects public policy regarding the issuance of digital certificates for a domain. If the domain doesn't have a CAA record for him, the certificate authority can issue her an SSL certificate for the domain. However, you can use this record to limit the certificate authorities that are authorized to issue digital credentials for your domain.
CNAME record lookup – Also known as canonical name or alias record used to refer to other DNS records. Often used for subdomains such as www. CNAME record: Also known as Canonical Name record, creates an alias for a domain name. Alias domains or subdomains hold all the DNS records of the original domain and are often used to associate a subdomain with an existing main domain.
MX record lookup – DNS records for mail exchangers are used to store email servers responsible for processing email for your domain name. MX record: Also known as a mail exchange record, indicates the mail exchange server responsible for routing mail to the proper destination or mail server. For detailed analysis, use MX record lookup. NS records: Also known as nameserver records, these are the nameservers responsible for managing and publishing the DNS records for your domain. These are the authoritative DNS servers that handle all queries related to this domain. Use the NS Lookup Tool to dig deeper.
PTR record lookup pointer or reverse DNS record. This is the opposite of an A or AAAA DNS record, which allows IP addresses to PTR record: An IPv4 or IPv6 address, also called a pointer record, points to a computer's host name. It provides reverse DNS records, also known as rDNS records, by specifying IP addresses for server hostnames. SRV record: Also called a service record, along with a port number, indicates the specific service your domain operates on. Some Internet protocols such as Extensible Messaging and Presence Protocol (XMPP) and Session Initiation Protocol (SIP) often require SRV records.
SOA Record Lookup- Start of Authority DNS records store meta details about a sphere name similar as the director contact dispatch address and when the sphere last had changes made to its DNS configuration. SOA Records: Also known as Start of Authority Records, they provide important information about a domain such as his identity in the authoritative domain name server master node, emails from domain administrators, and DNS zone serial numbers.
SRV Record Lookup- Service DNS records store protocol and harborage figures for services offered by the sphere name, for illustration VoIP or converse garçon.
TXT Record Lookup- Text records are used to store notes as DNS records, still they're generally used to store configuration settings for colorful services like SPF records which are used to define which dispatch waiters are allowed to shoot dispatch from the sphere or verification canons for some webmaster tools. TXT record: Allows website administrators to insert arbitrary text into DNS records.
DS record: Also known as a delegation signer record, it consists of the unique characters of the public key and associated metadata such as key tag, algorithm, digest type, and cryptographic hash called digest.
DNSKEY record: Also known as DNS key record, contains public signing keys such as zone signing keys (ZSK) and key signing keys (KSK). DS and DNSKEY records are used to verify the authenticity of DNS records returned by DNS servers.
Think of DNS lookups as maps or phonebooks to find and understand each lookup.
We all know that a correct address is required to reach a particular destination. All smart devices, phones, laptops, tablets, TVs, etc. communicate over the Internet using a series of numbers called IP addresses. A DNS server eliminates the need for humans to remember her complicated numeric IP address. DNS resolution translates human-friendly domain names into computer-friendly IP addresses. DNS servers take full responsibility for providing relevant results to users. As mentioned earlier, humans cannot learn long strings of numbers (IP addresses). So just entering the name of your website (www.amazon.com) will give your DNS server the IP address associated with that domain.
A DNS server can be located either at your ISP or on your local network. Translated domains (translated to IP addresses) are accessed by other devices, such as routers, and forward search results.
Now that you know how DNS lookups work, he goes on to explain the two main types... Forward DNS lookup Looking up the domain name of an IP address is called forwarding DNS lookup. A typical type allows users to enter a domain name and get the corresponding IP address.
Reverse DNS lookup
Unlike forward DNS lookups, reverse DNS lookups identify domain names by IP address. Email servers use this lookup method to identify valid recipients.
What are DNS records?
A DNS record is a mapping file that contains instructions for providing the following information related to your domain:
IP (IPv4/IPv6) is mapped to this domain. How are DNS requests for this domain handled? The DNS lookup tool retrieves all DNS records for your domain and reports them to your priority list. Use the options to perform a DNS lookup using Google, Cloudflare, OpenDNS, or your domain's authoritative nameservers. So when you change your web hosting or DNS records, those changes take effect immediately.
To ensure that your domain has the correct DNS records configured, use a DNS lookup tool to check your DNS records and avoid downtime. A, AAAA, CNAME, MX, NS, PTR, SRV, SOA, TXT, CAA, DS, DNSKEY, and other DNS entries are available.
Select any record to search, or select all to get all common DNS records for your domain.
