What is DNS propagation and how does it work?
When you update domain DNS records (such as migrating to a new web host, pointing an A record to a new IP address, or configuring MX records for business email), changes are not immediate worldwide. This gradual distribution process is known as DNS propagation.
Internet Service Providers (ISPs) and recursive DNS resolvers cache domain records for a specific duration determined by the TTL (Time to Live) parameter. Until this cache expires, visitors may still be routed to the old server. This tool allows you to monitor global propagation in real-time.
Supported DNS record types and their functions
| Record | Primary Function | Typical Value Example | Recommended TTL |
|---|---|---|---|
| A | Points the domain to a physical server IPv4 address. | 198.51.100.24 | 300s (migration) / 3600s |
| AAAA | Points the domain to a 128-bit modern IPv6 address. | 2001:0db8:85a3::8a2e | 3600s |
| CNAME | Canonical alias redirecting a subdomain to another domain hostname. | shop.wyrebase.com | 3600s |
| MX | Directs incoming emails to designated mail exchange servers. | 10 mail.wyrebase.com | 14400s |
| TXT | Stores machine-readable text for email verification (SPF, DKIM, verification). | v=spf1 include:relay.wyrebase.com -all | 3600s |
| NS | Delegates DNS zone authority to designated nameservers. | ns1.wyrebase.com | 86400s (24h) |
| SOA | Declares zone authority, administrative contact, and serial number. | ns1.wyrebase.com hostmaster.wyrebase.com 2026090801 | 86400s (24h) |
| CAA | Specifies which Certificate Authorities (CAs) are allowed to issue SSL certificates. | 0 issue "letsencrypt.org" | 3600s |

Frequently asked questions about DNS propagation
How long does full DNS propagation take?
DNS propagation typically takes anywhere from 15 minutes to 24 hours (rarely up to 48 hours for root NS changes). The timeframe depends primarily on the previous TTL settings of your zone.
Why do some regions resolve the new site while others do not?
Different ISPs and recursive resolvers update their internal caches at varying intervals. While modern public resolvers like Cloudflare (1.1.1.1) and Google (8.8.8.8) refresh strictly by TTL, some regional telecom providers hold records longer.
How can I speed up propagation before moving my website?
Best practice: lower your DNS record TTL to 300 seconds (5 minutes) about 24 to 48 hours prior to the migration. When you finally point the records to Wyrebase, the entire internet will pick up the new IP almost instantly.
What is the "Expected Value" feature?
Entering your target IP or hostname enables instant differential auditing. Every node is checked against your expected value, clearly highlighting which resolvers have completed propagation and which are still serving legacy data.
