What should my DHCP address be?
Since the default DHCP address range is between 100 and 149, you’ll want to avoid all of the addresses between 192.168. 1.100 and 192.168. 1.149 when you’re assigning static IP addresses. That leaves the ranges from 2-99 and from 150-254 wide open, which is usually plenty for most home networks.
What protocol could be used to issue an IP address and the IP address of the DNS server to network devices?
DHCP server
A DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks. DHCP is an enhancement of an older protocol called BOOTP. DHCP is an important part of the DDI solution (DNS-DHCP-IPAM).
What happens when DHCP runs out of addresses?
A router can run out of IP addresses to assign to your devices, although it is very unlikely to happen. If the DHCP server has already allocated all available addresses, the router will refuse to assign an IP address until an existing device releases an IP address or the DHCP lease time expires.
How can I change DHCP range in MikroTik?

How long does a DHCP address last?
between eight and 24 hours
On a typical home or small office router a DHCP lease may last between eight and 24 hours. Each time the lease is renewed (which happens automatically), there’s a chance the device will receive a different IP address.
Should I enable DHCP on router?
IMPORTANT: The IP Address has to be within the DHCP Reservation range. This is because you cannot set an IP reservation outside the DHCP range. QUICK TIP: The DHCP Server should be enabled because disabling it will make your router work as a switch, allowing only one (1) computer to have Internet access.
What is the difference between DHCP and DNS?
DNS is a decentralized system. DHCP is a centralized system. DNS Server translates domain names to IP addresses and vice versa. DHCP Server is used to configure hosts mechanically.
Which of the following is an automated mechanism used to assign IP addresses?

What would happen if we ran out of IP addresses?
Experts predict that within three years we will see the last of new Web addresses. What will happen then? The best solution is to create a market for already assigned but unwanted numbers, says Harvard Business School professor Ben Edelman.
How does DHCP assign IP addresses?
DHCP assigns an IP address when a system is started, for example:
- A user turns on a computer with a DHCP client.
- The client computer sends a broadcast request (called a DISCOVER or DHCPDISCOVER), looking for a DHCP server to answer.
- The router directs the DISCOVER packet to the correct DHCP server.
Can a server be assigned an IP address without DHCP?
If the IP address is manually assigned on a system, and not assigned by DHCP, then that record is registered by the system itself. In a production environment, most of the critical servers are having an IP address assigned directly and not through DHCP.
Is the DHCP server configured to perform DNS dynamic updates?
The DHCP server is configured to perform DNS dynamic updates on behalf of DHCP clients. The DNS zones to be updated by the DHCP server are configured to allow only secure dynamic updates.
How does a domain controller function as a DHCP server?
A domain controller is configured to function as a DHCP server The DHCP server is configured to perform DNS dynamic updates on behalf of DHCP clients. The DNS zones to be updated by the DHCP server are configured to allow only secure dynamic updates. Changing zone settings from non-secure to secure
What happens if one DHCP server crashes and crashes?
If one DHCP Server crashes, another DHCP server in the pool will be able to update those records registered by the previous server. This is because both servers are using the same user account to register DNS record, so ACL will not cause any problem.
