Question 1

What is DNS propagation?

Accepted Answer

DNS propagation is the time it takes for DNS changes to be updated across all DNS servers worldwide. When you update your domain's DNS records (like changing nameservers or adding a new A record), these changes need to spread to DNS servers globally. This process typically takes anywhere from a few minutes to 48 hours, depending on TTL (Time To Live) settings and individual server cache policies.

Question 2

Why do I see different results from different locations?

Accepted Answer

Different DNS servers cache records for varying lengths of time based on the TTL value. Some servers may have already updated with your new records, while others are still serving cached (old) data. This is completely normal during propagation. Large websites may also intentionally return different IPs based on geographic location for load balancing purposes.

Question 3

How long does DNS propagation take?

Accepted Answer

DNS propagation typically takes between 15 minutes to 48 hours, though most changes propagate within 1-4 hours. The actual time depends on: your DNS record's TTL value, how recently the record was cached by each server, and individual ISP caching policies. Lower TTL values (like 300 seconds) generally result in faster propagation.

Question 4

What do the different DNS record types mean?

Accepted Answer

A records point a domain to an IPv4 address. AAAA records point to IPv6 addresses. MX records specify mail servers for your domain. CNAME records create aliases pointing to other domains. NS records identify your domain's authoritative nameservers. TXT records store text data, often used for domain verification and email authentication (SPF, DKIM).

Question 5

Why are some locations showing red X marks?

Accepted Answer

A red X indicates that the DNS server at that location couldn't find a record for your query. This could mean: the record doesn't exist, propagation hasn't reached that server yet, or there's a temporary connectivity issue. If most locations show green checks, the red ones will likely update soon as propagation continues.

Question 6

How can I speed up DNS propagation?

Accepted Answer

While you can't directly control propagation speed, you can: lower your TTL values before making changes (ideally 24-48 hours in advance), use a reliable DNS provider with a global network, and ensure your records are correctly configured. After making changes, you'll need to wait for the old cached records to expire based on their TTL.
