Analyze whether your website's DNS changes (NS, A, MX, TXT) have reached servers worldwide via our interactive map. Detect regional access issues.
DNS (Domain Name System) is the phonebook of the internet. When you point a domain (diyovm.com) to an IP address (1.2.3.4), this information is not transmitted instantly to all DNS servers worldwide. This process is called **DNS Propagation**. It spreads gradually from your local ISP to Tier-1 backbone providers.
DNS changes usually take between **1 hour and 48 hours** to settle. The main reason is the **DNS Caching** mechanism. ISPs (like Comcast, Verizon, etc.) store DNS records on their servers to speed up traffic. Even if you change the record, your ISP might route users to the old server until the cache expires (based on TTL).
| Record Type | Description & Usage |
|---|---|
| A | Points a domain to an IPv4 address (Ex: 192.168.1.1). |
| CNAME | Points a domain to another domain name (Alias). |
| MX | Specifies Mail Exchange servers. Essential for receiving emails. |
| TXT | Text records. Used for SPF, DKIM, and ownership verification (Google). |
| NS | Nameserver records. Indicates which hosting company manages the domain. |
