How IP Addresses Are Divided
IP addresses (IPv4) are 32-bit binary numbers usually shown in dotted decimal format (e.g., 192.168.1.1). They're divided into two parts:
✅ Network Portion & Host Portion
✅ Subnetting
🔹 2. How IPs Are Assigned Automatically (DHCP)
Devices on a network can get IP addresses automatically using a DHCP server (Dynamic Host Configuration Protocol).
🖥️ How DHCP Works (Step-by-Step):
-
Device connects to the network and sends a DHCP Discover message.
-
DHCP server responds with a DHCP Offer (includes an available IP address).
-
Device sends a DHCP Request to accept the offer.
-
DHCP server confirms with a DHCP Acknowledgment.
-
Device is now assigned an IP address for a limited lease time.
🛠️ DHCP Server Can Assign:
-
IP address
-
Subnet mask
-
Default gateway
-
DNS server(s)
🔸 Example Setup
In a small office network:

🔸 Example Setup
In a small office network:
-
The router or a dedicated server (e.g., Windows Server, Linux, pfSense) runs the DHCP service.
-
It assigns IPs like 192.168.1.100 to 192.168.1.200 to devices automatically.
