What is a DNS lookup?
DNS (Domain Name System) translates domain names into the IP addresses and mail server information that the internet needs to route traffic. This tool queries the authoritative DNS servers for a domain and returns all available record types.
Record types explained
- A - IPv4 address (where the website lives)
- AAAA - IPv6 address
- MX - Mail exchanger; priority + hostname of mail server(s)
- NS - Nameservers authoritative for this domain
- TXT - Text records; contain SPF, DMARC, Google verification, and more
- CNAME - Canonical name alias pointing to another hostname
- SOA - Start of Authority; primary nameserver and zone metadata
- CAA - Certificate Authority Authorization; which CAs may issue SSL certs
What is DNSSEC?
DNSSEC adds cryptographic signatures to DNS records, preventing DNS spoofing and man-in-the-middle attacks on DNS resolution.
