DNS Propagation and Changing Nameservers

1. Introduction

When you click a link or enter a domain name, your browser must convert that name into an IP address. This DNS resolution involves several caching layers and can take time to propagate globally.

2. DNS Resolution Flow

The typical lookup sequence is:

• Browser cache: check for stored IP.
• OS cache: query the operating system’s DNS cache.
• Local DNS/router: use the network’s configured DNS server.
• ISP DNS: if unresolved, ask your Internet provider’s DNS.
• Authoritative DNS: ISP servers follow referrals until reaching the registrar’s DNS.
• Hosting nameservers: the authoritative DNS for your host (e.g., ns1.mioritichost.com) returns the A record.

“Without a complete DNS chain, your browser has no way to locate the website’s server.”

3. What Is DNS Propagation?

DNS propagation is the period during which DNS caches around the world update after a change—such as switching nameservers or editing records. Each cache respects the record’s TTL (Time To Live) before refreshing.

4. Why Does It Take Up to 48 Hours?

• Existing TTL values: records can be cached for minutes or several hours.
• Multiple caching layers: browser, OS, router, ISP, and more.
• Global distribution: DNS servers across different regions.

5. Tips to Speed Up Propagation

• Avoid repeated visits right after the change to preserve local TTLs.
• Clear your browser cache.
• Flush the OS DNS cache: e.g., ipconfig /flushdns on Windows.
• Schedule changes off-peak: perform updates in the evening or low-traffic hours.

6. Changing Nameservers at Mioritichost

To point your domain to Mioritichost, set these nameservers:

ns1.mioritichost.com  
ns2.mioritichost.com

• Log into your domain registrar.
• Open the “Nameservers” or “DNS Management” section.
• Replace the old nameservers with Mioritichost’s and save changes.

“A single nameserver update reroutes all domain traffic to your new hosting in one go.”

7. Monitoring and Verification

After saving, use online tools (e.g., WhatsMyDNS.net) to track propagation. Within 4–48 hours, you should see all locations pointing to your Mioritichost setup.

8. Conclusion

By understanding the DNS lookup process and TTL, you can manage propagation time effectively. Correctly configuring ns1.mioritichost.com and ns2.mioritichost.com, and following the acceleration tips, ensures minimal downtime and reliable access to your site.
