DHCP
Dynamic Host Configuration Protocol (DHCP) servers provide network configuration parameters to machines when they boot. DHCP provides the IP addresses, subnet mask,
the broadcast address, the IP address of the default gateway, the IP address of one or more DNS servers, a domain name for the client and so on.
DHCP offers a number of conveniences. First, it allows large-scale deployment of desktop systems by allowing each system to be imaged with an identical configuration. Second, it allows those who regularly move laptops between networks to automatically pick up appropriate settings for that network, without tedious manual reconfiguration. Third, it allows reuse of IP addresses through the reclamation and reissue of expired leases.
Server တြင္ DHCP အသံုးၿပဳထားပါက Network အတြင္းရွိ Devices မ်ားအား IP Numbers မ်ား Assign ၿပဳလုပ္ရန္မလုိအပ္ပါဘူး။ အလြန္ၾကီးမားတဲ့ Network မ်ားမွာ IP Numbers မ်ားခြဲေ၀သံုးစြဲရာမွာ Client တုိင္းဟာ တစ္ဦးခ်င္းတပ္ဆင္သံုးစြဲရမွာၿဖစ္ပါတယ္။ ဒါ့ေၾကာင့္သာမာန္ User မ်ားအေနဲ႔ ၀င္ ေရာက္သံုးစြဲရန္ ခက္ခဲမည္ၿဖစ္လို႔ Network Administrator ကလဲစီမံထိန္းခ်ဳပ္ဖုိ႔ခက္ခဲ ရႈပ္ေထြးမွာၿဖစ္ပါတယ္။ DHCP Server သံုးစြဲၿခင္းအားၿဖင့္ Specialized Server မ်ားအား Fixed IP Number ခြဲေ၀ေပးထားသည္မွလြဲၿပီးက်န္ Client မ်ားအား IP သက္မွတ္ေပးဖို႔လိုအပ္မွာမဟုတ္ေတာ့ပါဘူး။ DHCP မွ၀င္ေရာက္လာတဲ့ စက္မ်ားကို သက္မွတ္တဲ့အခ်ိန္ပိုင္း (Lease Time) မ်ားအလိုက္ IP မ်ားကို အလိုအေလွ်ာက္ခြဲေ၀သက္မွတ္ေပးသြားမွာၿဖစ္ပါတယ္
