\n\n\n\n\ud83c\udf10 What is NAT (Network Address Translation)?<\/h2>\n\n\n\n
NAT<\/strong> stands for Network Address Translation<\/strong>. It’s a method used by routers to allow multiple devices on a private network (like your home or office) to share a single public IP address when accessing the internet.<\/p>\n\n\n\n\ud83e\udde0 Why NAT Exists<\/h2>\n\n\n\n\n- Most homes and small networks use private IP addresses<\/strong> (e.g.,
192.168.x.x<\/code>)<\/li>\n\n\n\n- These addresses aren\u2019t routable on the internet<\/strong><\/li>\n\n\n\n
- NAT translates these private IPs into a single public IP<\/strong> so devices can communicate externally<\/li>\n<\/ul>\n\n\n\n
\ud83d\udd01 How NAT Works (Simplified)<\/h2>\n\n\n\n\n- Your laptop (IP:
192.168.1.10<\/code>) wants to visit example.com<\/code><\/li>\n\n\n\n- Router replaces your IP with its public IP (e.g.,
73.45.22.8<\/code>) and sends the request<\/li>\n\n\n\n- When the response comes back, the router remembers<\/strong> who asked and forwards it to your laptop<\/li>\n<\/ol>\n\n\n\n
\ud83e\uddf1 Types of NAT<\/h2>\n\n\n\nType<\/th> Description<\/th><\/tr><\/thead> Static NAT<\/strong><\/td>One-to-one mapping between internal and external IP<\/td><\/tr> Dynamic NAT<\/strong><\/td>Maps internal IPs to a pool of public IPs<\/td><\/tr> PAT (Port Address Translation)<\/strong><\/td>Most common; many internal IPs share one public IP using different ports<\/td><\/tr> NAT Loopback (Hairpin NAT)<\/strong><\/td>Allows internal devices to access the router\u2019s public IP as if they were external<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n\u2705 Benefits of NAT<\/h2>\n\n\n\n\n- Conserves public IP addresses<\/li>\n\n\n\n
- Adds a layer of security by hiding internal IPs<\/li>\n\n\n\n

\n\n\n\n\ud83c\udf10 What is NAT (Network Address Translation)?<\/h2>\n\n\n\n
NAT<\/strong> stands for Network Address Translation<\/strong>. It’s a method used by routers to allow multiple devices on a private network (like your home or office) to share a single public IP address when accessing the internet.<\/p>\n\n\n\n\ud83e\udde0 Why NAT Exists<\/h2>\n\n\n\n\n- Most homes and small networks use private IP addresses<\/strong> (e.g.,
192.168.x.x<\/code>)<\/li>\n\n\n\n- These addresses aren\u2019t routable on the internet<\/strong><\/li>\n\n\n\n
- NAT translates these private IPs into a single public IP<\/strong> so devices can communicate externally<\/li>\n<\/ul>\n\n\n\n
\ud83d\udd01 How NAT Works (Simplified)<\/h2>\n\n\n\n\n- Your laptop (IP:
192.168.1.10<\/code>) wants to visit example.com<\/code><\/li>\n\n\n\n- Router replaces your IP with its public IP (e.g.,
73.45.22.8<\/code>) and sends the request<\/li>\n\n\n\n- When the response comes back, the router remembers<\/strong> who asked and forwards it to your laptop<\/li>\n<\/ol>\n\n\n\n
