What Are Nameservers?
DNS propagation is the process of updating DNS (Domain Name System) records across the internet. Here’s a simplified explanation:
What happens during DNS propagation:
1. DNS record update: You update your domain’s DNS records (e.g., A, MX, CNAME) at your DNS provider or registrar.
2. Propagation starts: The updated records are sent to the root DNS servers and then distributed to other DNS servers worldwide.
3. Caching and refreshing: DNS servers cache the old records for a period (TTL – Time To Live). As the TTL expires, they refresh the records by querying the authoritative nameservers.
4. Global update: The updated records are gradually propagated to all DNS servers, replacing the cached old records.
Factors affecting DNS propagation:
1. TTL (Time To Live): Affects how long DNS servers cache records.
2. DNS server hierarchy: Updates propagate from root to top-level domain (TLD) to authoritative nameservers.
3. Internet connectivity: Network congestion or outages can slow propagation.
4. DNS provider or registrar: Efficiency of their DNS infrastructure and update mechanisms.
Propagation timeline:
1. Typical: 24-48 hours for most DNS providers.
2. Fast: Some providers like Vikalink offers faster propagation (e.g., 1-4 hours). Vikalink offers 30 seconds of propagation time to enable faster DNS update.
3. Slow: Propagation can take up to 72 hours or more in some cases.
Keep in mind that DNS propagation is a complex process, and timelines may vary. If you have specific questions or concerns about DNS propagation, feel free to ask!
