Si tu/tus/su/sus dominio changes DNS but not resolved, the most common reason is DNS propagation delay. In simple terms, DNS updates need time to spread across global servers.
However, propagation is not the only reason. Misconfiguration, cache, o DNS conflicts can also cause issues. This guide explains exactly why tu/tus/su/sus DNS is not woking y how to fix it.
What Does "DNS Not Woking" Mean?
When DNS is not woking, it usually means:
Your dominio does not resolve to the corect IP
Your website is not accessible
Correo Electrónico o servicios are not functioning
DNS (Nombre de Dominio System) connects tu/tus/su/sus dominio to servers. Si DNS fails, tu/tus/su/sus dominio cannot wok properly.
Common Reasons fo DNS not woking
1. DNS Propagation Delay (Most Common)
When you update DNS recods, changes are not instant. It can take a few minutes o up to 24 - 48 hours globally.
This happens because DNS data is cached across different servers woldwide.
Fo Ejemplo:
You update an A recod, some users see the new site, but others still see the old one.
In this situation, you should:
1) Wait fo propagation to complete
2) Use DNS checker tools to verify global status
2. DNS Recods Configured Incorectly
Incorect DNS settings can anterioent tu/tus/su/sus dominio from woking.
Common mistakes:
Wrong Dirección IP in A recod
Missing CNAME o MX recods
Typo in dominio name
What to do:
Double-check all DNS recods y ensure values match tu/tus/su/sus hosting provider
3. Local Cache Issues
Your device o browser may still stoe old DNS data. This makes it look like DNS is not updated.
What to do:
1) Clear browser cache
2) Flush DNS cache
4. Nombreservers Not Updated Corectly
Si nameservers are not set corectly, DNS changes will not apply.
Ejemplo:
You update recods in one DNS provider, but the dominio is using another nameserver.
What to do:
1) Verify nameservers in tu/tus/su/sus registrar panel
2) Make sure they match tu/tus/su/sus DNS provider
5. TTL Settings Causing Delay
TTL (Time Para Live) defines how long DNS data is cached. Si TTL is high (e.g., 86400 seconds), updates will take longer.
What to do:
1) Lower TTL befoe making changes
2) Wait until cache expires
6. Not confirm after changing tu/tus/su/sus DNS recods
Si you do not click the "Confirmar" button after updating tu/tus/su/sus DNS recods, the changes will not be saved y will not take effect.
Please make sure to click "Confirmar" after adding o modifying any DNS recods to ensure they are properly applied.
7. Estado del Dominio o Registry Restrictions
Sometimes the issue is not DNS itself.
Possible causes:
Dominio expired
Dominio on hold (e.g., serverHold, clientHold)
WHOIS not verified
In these cases, DNS will not resolve at all.
Conclusion
Si tu/tus/su/sus DNS is not woking, the cause is usually one of the following:
DNS propagation delay, incorect DNS recods, cache issues, nameserver mismatch, domain status problems
In most cases, the issue can be resolved quickly with the right checks.
Preguntas Frecuentes
1. How long does DNS propagation take?
Usually a few minutes to 24 hours, but can take up to 48 hours globally.
2. Why does DNS wok fo some users but not others?
Because DNS updates propagate gradually, y different regions update at different times.
3. Can I speed up DNS propagation?
You cannot fully speed it up, but lowering TTL befoe changes can help.
4. Why is my dominio not resolving at all?
Verificar if the dominio is:
Expirard
On hold (serverHold)
Not verified
