  1. Windows Server 2008 R2 DHCP Kurulum ve Yenilikler • Gökhan KESKİN • MCITP / MCT • gokhan.keskin@bilisimegitim.com

  2. Ajanda • Genel Bakış • Windows Server 2008 R2 ile gelen yenilikler • DHCP Çalışma Mantığı • DHCP Uygulamalarını Planlamak • DHCP Sunucularını Kurmak • Uygulama • Sorular

  3. Genel Bakış • DHCP’yi neden kullanıyoruz? • IP adreslerini otomatik dağıtmak • Konfigürasyonumuzdan emin olmak • Otomatik güncelleştirmeler • Çıkabilecek network sorunlarını indirgemek • Daha az enerji ve daha az efor !

  4. Windows Server 2008 R2 ile Gelen Yenilikler • DHCPv4 • DHCPv6 • Stateful & Stateless modeli • MAC Filter • Service Hardening • SplitScope • Activity Logging • DHCPv6’da Option15 ve Option32

  5. Çalışma Mantığı DHCP Client2:IP configuration from DHCP server Non-DHCP Client:Static IP configuration Lease Renewal Lease Generation DHCP Server DHCP Database DHCP Client1:IP configuration from DHCP server IP Address1: Leased to DHCP Client1 IP Address2: Leased to DHCP Client2 IP Address3: Available to be leased

  6. DHCP client broadcasts a DHCPDISCOVER packet 1 DHCP servers broadcast a DHCPOFFER packet 2 DHCP client broadcasts a DHCPREQUEST packet 3 DHCP Server1 broadcasts a DHCPACK packet 4 Çalışma Mantığı DHCP Server2 DHCP Server1 DHCP Client

  7. DHCP Server2 DHCP Client DHCP Server1 DHCP Client sends a DHCPREQUEST packet 1 DHCP Server1 sends a DHCPACK packet 2 How DHCP Lease Renewal Works 50% of lease duration has expired 87.5% of lease duration has expired 100% of lease duration has expired If the client fails to renew it’s lease, after 87.5% of the lease has expired, then the DHCP lease generation process starts over again with a DHCP client broadcasting a DHCPDISCOVER If the client fails to renew its lease, after 50% of the lease duration has expired, then the DHCP lease renewal process will begin again after 87.5% of the lease duration has expired
