DNS Check is a command-line tool that helps you verify if a list of websites can be accessed through specific DNS server. The tool reads a list of DNS servers from a file (dns.txt), takes one or more website addresses as command-line arguments, and checks if each website can be opened with the provided DNS servers.
- Custom DNS Server List: Specify DNS servers in
dns.txtwith the formatname=ip. - Multi-site Checking: Pass one or more website addresses as arguments to check their availability.
- DNS Resolution Test: For each DNS server, the program attempts to resolve and access the websites provided.
-
Prepare the DNS server list:
Create or modify the
dns.txtfile in the project directory. The file should contain the DNS server name and IP in the following format:cloudflare=1.1.1.1 google=8.8.8.8
-
Run the program:
Pass one or more website addresses as arguments (without
http://orhttps://). For example, to checkexample1.comandexample2.com:./dns-check example1.com example2.com
-
The program will attempt to resolve each website using each DNS server from the
dns.txtfile and display whether the website can be accessed.
