Here's how to Flush DNS on Windows/Mac/Linux/Andoid/iOS.

i. Flushing the DNS cache for a website is not something you can do directly as a user visiting the website. DNS (Domain Name System) caching is primarily managed by your operating system and web browser. However, if you want to ensure that you are accessing the latest DNS information for a specific website, you can follow these general steps:

### Clear DNS Cache on Windows:

1. **Command Prompt (Admin):**
- Open the Command Prompt as an administrator. Right-click on the Start button, select "Command Prompt (Admin)."
- Type the following command and press Enter: `ipconfig /flushdns`

### Clear DNS Cache on macOS:

1. **Terminal:**
- Open the Terminal application (you can find it in Applications - Utilities).
- Type the following command and press Enter: `sudo dscacheutil -flushcache`
- You may need to enter your admin password.

### Clear DNS Cache on Linux:

1. **Systemd-based Systems (e.g., Ubuntu 16.04 and later):**
- Open a terminal.
- Type the following command and press Enter: `sudo systemd-resolve --flush-caches`

2. **Debian-based Systems (e.g., Ubuntu 14.04 and earlier):**
- Open a terminal.
- Type the following command and press Enter: `sudo /etc/init.d/nscd restart`

### Clear DNS Cache in Web Browsers:

1. **Google Chrome:**
- Open a new tab and type `chrome://net-internals/#dns` in the address bar.
- Click "Clear host cache."

2. **Mozilla Firefox:**
- Open a new tab and type `about:config` in the address bar.
- Search for `network.dns.cache.entries` and set it to 0.

3. **Microsoft Edge:**
- Open a new tab and type `edge://net-internals/#dns` in the address bar.
- Click "Clear host cache."

### Note:

- Flushing the DNS cache can help if you're experiencing issues accessing a website due to outdated DNS information. However, it may not always be the solution, and there could be other factors affecting website access.

- If you're trying to update DNS records for your own website, you may need to wait for DNS propagation, which can take some time.

- If you're dealing with a specific issue or error when accessing a website, it's a good idea to investigate further or contact the website's administrator for assistance.
