DNS Lookup, What it is?
Genelify DNS Lookup or Checker is a simple tool to analyze DNS records on domain such as MX, CNAME, A, TXT, NS and others records.
Domain Name System is a system used to convert a name (like www.google.com) into an IP address (like 192.168.1.1). These addresses are used by computers to communicate with each other on the internet.
You can monitor records on domain, there are often multiple record types that you need to verify are correct. For example, websites sometimes include www or other subdomains as either an A or CNAME record, and email servers use the MX record type.
Knowing the elements in DNS lookup
DNS stands for Domain Name System, which means the name of a domain from an IP address to identify a domain so that it can be found easily. DNS functions so that the domain can be user-friendly, it is impossible for you as a user to visit a website to know what the IP address of the website is, therefore DNS is needed to convert IP addresses into domain names.
There are 2 ways DNS works:
1. Forwarding
Forwarding will search the domain name to find the IP address, this typically allows the user to enter the domain name to get the respective IP.
2. Reversing
Reversing is the opposite of Forwarding Lookup, which means identifying domain names by IP addresses.
To check whether you have configured your domain's records correctly, you can use this tool to view the contents of your domain's records including A, AAAA, CNAME, MX, NS, SOA, TXT, DS etc.
1. Records
This type is the most basic type which is also known as address records, IPv4 addresses into domain names or sub-domains. TXT shows the domain name to IP.
2. AAAA
This type maps hostnames into IPv6 addresses, the four "A" or AAAA stating that IPv6 is four times larger than IPv4.
3. CNAME
CNAME also known as a canonical name or creating an alias of a domain, domain or sub-domain alias will get all the records of the original domain used to connect the sub-domain with the main domain.
4. MX
MX or Mail Exchange is used for email, MX is useful for telling which email server is responsible for routing to the correct destination.
5. NS
NS or Name Server, regulates which server has the authority to manage and issue from the domain.
6. TXT
TXT allows administrators to enter any arbitrary text into records.
With each of the above information, you can find out what the purpose of the results that our system produces so that you can monitor every element in your domain's records.
