Tujuan Praktikum

• Melakukan konfigurasi DHCP Server di Linux menggunakan paket isc-dhcp-server.
• Menentukan interface jaringan dan parameter pool IP (subnet, range, router, reservation MAC).
• Melakukan konfigurasi DHCP Server di Router MikroTik menggunakan wizard interaktif.
• Memeriksa status service dan tabel sewa IP (leases).

Bagian A: DHCP Server Linux (Ubuntu/Debian)

1. 1. Install Paket isc-dhcp-server
   sudo apt update
   sudo apt install isc-dhcp-server -y
2. 2. Tentukan Interface Jaringan

   Edit file /etc/default/isc-dhcp-server:

   sudo nano /etc/default/isc-dhcp-server

   Ubah baris interface menjadi:

   INTERFACESv4="ens33"
3. 3. Atur Pool Alamat IP & Parameter

   Edit file utama /etc/dhcp/dhcpd.conf:

   sudo nano /etc/dhcp/dhcpd.conf

   subnet 192.168.10.0 netmask 255.255.255.0 {
     range 192.168.10.50 192.168.10.200;
     option domain-name-servers 8.8.8.8, 1.1.1.1;
     option domain-name "skil.local";
     option routers 192.168.10.1;
     option broadcast-address 192.168.10.255;
     default-lease-time 600;
     max-lease-time 7200;
   }
   
   host Printer-Office {
     hardware ethernet 00:11:22:33:44:55;
     fixed-address 192.168.10.25;
   }

4. 4. Restart & Uji Status Service
   sudo systemctl restart isc-dhcp-server

   sudo systemctl status isc-dhcp-server

Bagian B: DHCP Server di Router MikroTik

1. 1. Atur IP Address Interface Router

   Pindah ke tab [admin@MikroTik] di sebelah kanan, lalu jalankan:

   /ip address add address=192.168.20.1/24 interface=ether2
2. 2. Jalankan DHCP Setup Wizard
   /ip dhcp-server setup

   Isi parameter wizard berikut saat diminta:

   • Interface: ether2
   • DHCP Address Space: 192.168.20.0/24
   • Gateway for Network: 192.168.20.1
   • Addresses to Give Out: 192.168.20.10-192.168.20.100
   • DNS Servers: 8.8.8.8, 8.8.4.4
   • Lease Time: 03:00:00
3. 3. Cek Daftar Sewa IP (Leases)
   /ip dhcp-server lease print
