DNS Lookup

Check DNS records for any domain and inspect how the domain resolves across common DNS record types.

What Is a DNS Lookup?

A DNS lookup checks the Domain Name System records associated with a domain name. DNS translates human-readable domain names such as example.com into information that computers and network services can use.

ALVIX DNS Lookup lets you inspect several common DNS record types for a domain, including A, AAAA, CNAME, MX, NS, and TXT records.

What is an A record?

An A record maps a domain name to an IPv4 address. It is commonly used to determine which IPv4 server a domain points to.

What is an AAAA record?

An AAAA record maps a domain name to an IPv6 address. It serves a similar purpose to an A record but uses the newer IPv6 addressing system.

What is a CNAME record?

A CNAME record creates an alias from one hostname to another hostname. It is commonly used when a service or subdomain should point to another canonical hostname.

What is an MX record?

MX records identify the mail servers responsible for receiving email for a domain. The priority value determines the preferred order when multiple mail servers are configured.

What is an NS record?

NS records identify the authoritative name servers responsible for DNS information for a domain. They are an important part of the domain's DNS delegation.

What is a TXT record?

TXT records store text associated with a domain. They are commonly used for domain verification, email authentication, SPF information, and other service-specific configuration.

DNS Lookup FAQ

How do I check DNS records for a domain?

Enter the domain name into the ALVIX DNS Lookup field and select Lookup DNS. The tool will display the DNS record types that are available for the domain.

What DNS records can ALVIX check?

ALVIX currently checks common A, AAAA, CNAME, MX, NS, and TXT records.

Why does a domain have multiple DNS records?

A domain can use multiple records for different purposes. For example, a domain may have several A records for multiple servers and multiple MX records for email delivery.

Why are some DNS records missing?

Not every domain uses every record type. A domain may also use DNS records that this tool does not currently query.

How long does a DNS change take to appear?

DNS changes can take time to appear across different DNS resolvers because DNS data is cached according to its configured TTL.
