Question
Consider the types of systems that benefit from DHCP reservations and/or from having manually-configured (static) IP addresses, including servers, networked printers, and other networked devices (e.g., network-connected HVAC controllers, IP camera systems). One option is to configure DHCP reservations and allow the devices to use DHCP to consistently get the same address; another option is to configure static addresses on the devices themselves and leave the addresses out of any DHCP scopes (or just to reserve them in DHCP). For the scenarios mentioned above (e.g., servers, networked printers, other similar networked devices), would you recommend static configuration on the devices or DHCP reservations? Why? Are some types of devices better suited to DHCP than others?
Explanation / Answer
DHCP reservation:
Advantages:
1) offers easy maintanance of IP addresses
2) You can check whether a IP is allocated or not using DHCP table
3) You can write the comments , when allocating the IP addresses, such as (to which device it is allocated, location of the device etc...)
4) usefull when you keep on changing OS of the device
based on the all above reasons it is better to use DHCP reservation than static IP allocation
BUT
if some devivce does not support DHCP reservation , then use STATIC IP allocation for than and make a reservation of that IP , so that that IP will not be allocated to other device by mistake
The devices which are very critical should use static IP, as any attacks on DHCP server will affect the devices which are using IP addresses allocated by this DHCP server
The devices in which we change OS very frequently are more benifited by DHCP reservation than othsers (because if we use static IP for this we have configure IP , every time we change the OS)
