dns propagation check

dig 

DNS propagation refers to the time it takes for DNS changes to be updated across all DNS servers globally. When you make changes to your domain’s DNS records, such as updating an IP address or changing nameservers, these updates may not be immediately visible to everyone due to caching. This page provides tools to check the current DNS records of your domain and verify that the changes have propagated successfully.

Tools for DNS Propagation Check

1. dig

dig (Domain Information Groper) is a powerful command-line tool used for querying DNS records. It can provide detailed information about the DNS records for a domain and can query specific DNS servers.

Basic Usage:

> dig @<DNS_SERVER> <DOMAIN> <QUERY_TYPE>

Example:

> dig @8.8.8.8 example.com A

This command queries the A record for example.com from Google’s public DNS server (8.8.8.8).

2. nslookup

nslookup is another command-line utility for querying DNS to obtain domain name or IP address mapping. It’s straightforward and widely used for checking DNS information.

Basic Usage:

> nslookup -type=<QUERY_TYPE> <DOMAIN> [<DNS_SERVER>]

Example:

> nslookup -type=MX example.com

This command retrieves the MX (Mail Exchange) records for example.com.

3. host

The host command is a simple utility for performing DNS lookups. It is typically used to find the IP address associated with a domain or to find the domain associated with an IP address.

Basic Usage:

> host -t <QUERY_TYPE> <DOMAIN> [<DNS_SERVER>]

Example:

> host -t TXT example.com

This command queries the TXT records for example.com.

Using these tools, you can effectively check the DNS records for your domain and confirm that any changes have propagated. By querying different DNS servers, you can gain insights into how your DNS records are resolving across the internet.
