DNS (Domain Name System) records tell browsers, mail servers and other services how to reach your website and related services. When you change hosting, email or verification settings, you are usually updating DNS records at your domain registrar or DNS provider.
Each record type answers a different question: where a website lives, where email should be delivered, which servers are authoritative for a domain, or which text tokens prove ownership.
A records point a hostname to an IPv4 address. AAAA records do the same for IPv6. Together they control where web traffic is sent.
MX records define mail servers and their priority order. TXT records store plain text used for SPF, DKIM setup hints, domain verification tokens and other policy strings.
NS records list the authoritative nameservers for a domain. CNAME records alias one hostname to another, which is common for subdomains pointing at a platform host name.
Enter a domain or URL, choose a record type (or ALL), then click Lookup. Results appear grouped by type with TTL values when the resolver provides them. Use copy buttons to grab individual values for tickets or documentation.
DNS responses are cached according to each record’s TTL and by resolvers along the way. After you change DNS at your provider, it can take from a few minutes to 48 hours for everyone to see the update, depending on old TTL values and caching.
