Frequently Asked Questions
What are DNS records?
DNS records are entries in the Domain Name System that map domain names to IP addresses and other information. They tell the internet where to find your website, email servers, and other services.
Common types include A records (IPv4 addresses), AAAA records (IPv6), CNAME records (aliases), MX records (mail servers), NS records (name servers), and TXT records (text data).
Every domain that works on the internet has at least some DNS records configured.
What is an MX record?
MX (Mail Exchange) records specify the mail servers responsible for receiving email for a domain. Each MX record has a priority value where lower numbers indicate higher priority.
If the highest priority server is unavailable, email is delivered to the next one in the list.
Checking MX records is essential for troubleshooting email delivery problems.
What is TTL?
TTL (Time To Live) is the number of seconds a DNS record is cached by resolvers before they query the authoritative server again.
Lower TTL values mean changes propagate faster but increase the load on DNS servers. Higher values improve performance but delay propagation of changes.
Typical TTL values range from 300 seconds (5 minutes) to 86400 seconds (24 hours).
Why do I see different results from different locations?
DNS records can take time to propagate globally after changes. Different DNS resolvers may have cached older versions of the records based on their TTL values.
Some domains also use GeoDNS to return different IP addresses based on the querying location for load balancing and performance.
Full propagation typically takes 24 to 48 hours after a DNS change, though most resolvers update much sooner.
