DNS Lookup Tool

Quickly performs a number of DNS and IP lookups.
Example Searches:
< blank >
— Your current IPv4 or IPv6 address
— IPv4 address search, CloudFlare Public DNS
— IPv6 address search, Google Public DNS
— DNS search, this web site
— URL search, IP info web site

The tool searches are somewhat recursive, so a lot of relevant information is shown right away.

Built using free web services from CloudFlare & ipinfo.io .

The IPv4 address locates a host on the Internet. It is still commonly used, but has been superseded by the newer IPv6 standard.
The IPv6 address locates a host on the Internet. Support is still not universal, but IPv6 should obsolete IPv4 eventually.
The DNS A record maps a name to an IPv4 address.
The DNS AAAA record maps a name to an IPv6 address.
The DNS PTR record maps an IP address to a name. It is used for reverse IP lookups.
The DNS CNAME record is the equivalent of a redirect or an alias. The referenced name is specified as a fully qualified DNS name.

Any recursive DNS lookup (A, AAAA, MX, etc) will use the referenced name instead. The CNAME record is normally only used for subdomains, such as www.domain.tld.
The DNS MX record specifies an mail server for the zone (domain). The data format is priority hostname.

The priority is a decimal number, where lower values have precedence over higher. The hostname is a fully qualified DNS name for an SMTP mail server.
The DNS TXT record may contain any information, but it commonly contains the SPF, DKIM or DMARC policies for the zone (domain) in machine readable form.
The DNS NS record specifies the authoritative DNS server for the zone (domain). The server is specified as a fully qualified name and points to a DNS server.
The DNS SOA record specifies authoritative information about a zone (domain).
