DHCP vs Static IP: Difference Between DHCP and Static IP

Most media devices like network switches or routers use IP protocol as the standard. The simplest way of accomplishing this configured IP address or a fixed IP address. Some administrators attempt to use IP as there are limits to IP. Let's learn about the differences of DHCP vs Static IP.

DHCP is a protocol for allowing dynamic IP addresses to devices which connected to the network.

In a Control system, most network elements require an IP address. Items on the Zigbee network, such as switches, network-enabled televisions, networked receivers, speaker points, and other connected devices all have to be on the system either through Ethernet or a wireless link. This is done with IP (Internet Protocol) addressing.

DHCP vs Static IP: Comparison Table

DHCP

Static IP

A temporary IP address that is attached to a device or a node when it connects to a network.​​​​​

A constant numeric address manually attached to a device in the network.

It is assigned by the DHCP server automatically.

Assigned manually by the network executive.

Suitable for an extensive network requires internet access to all devices.

Proper for dedicated services such as mail, VPN server, and FTP.

Assigning is easier.

Assigning is challenging.

More secure.

Limited secure.

Settings each time the device connects to the network.

Does not change once it assigns to a device.

What is Static IP address?

A static IP address is an approach that is assigned to your own network devices by your ISP and doesn't change even if your device reboots. Static IP addresses have two versions: IPv4 and IPv6. Static routing is a function for today's network switches. Many of FS switches feature paths, such as FS S5900-24S switch which helps both IPV4 and IPV6. IP address that is static generally assigned to a host hosting sites and offers FTP, VPN and email services.

In static IP addressing, every device on the network has its speech with no overlap. And you will have to configure the IP addresses. When new devices are attached to a system, you may need to select the “manual" arrangement option. Like input the IP address, the default gateway, the subnet mask, and the DNS server.

With static IP addressing, addresses are attached manually and need to be provisioned carefully. So that every device has its speech --with no overlap. If you knew any of what I said, you have the knowledge and the skills required to manage IP addresses. You would probably be more comfortable with DHCP if it had been gibberish.

Static IP Address Example

A typical example of using a static IP address is a network server. From the Window on computer, go to

START -> RUN -> type “cmd” -> OK.

Next type “ping www.google.com” on the Command Window. The four-byte number 73.125.127.147 is the popular IP for www.google.com. If it exists a static IP, you would be capable of connecting Google at any time by doing this static IP address in the web browser if you want to visit Google.

Advantages of Static IP address

  • Using DNS to map a domain name to an IP address. And using the domain name to address the static IP address.
  • The address does not vary over time unless it is changed manually - suitable for web servers.

Disadvantages of Static IP address

  • Requiring additional security and standard form. Which adds complexity when large numbers of devices are connected.
  • Costly than dynamic IP address - ISP generally charges an extra fee for static IP addresses.

What is DHCP server?

Dynamic Host Configuration Protocol is a protocol applied to provide automatic, quick, and center management for the configuration of IP addresses in a network. DHCP is also handled to configure the proper subnet default gateway, mask, and DNS server information on the device.

The system has to have a DHCP server to make IP addresses. The DHCP server assigns an IP address that is vacant to all devices. DHCP is a method of automatic and dynamically assigning IP addresses to network devices on a physical network. It offers an automated method update and to distribute other configuration information and IP addresses. Thus, DHCP over IP address' benefit is that DHCP doesn't require any configuration gain access or to connect to local devices.

On which layer of OSI model DHCP works?

DHCP operates on Layer 2 in the OSI model. 

This means that if a device needs a dynamic IP address, it can only request one on the same network that it's present on. The DHCP architecture consists of DHCP clients, DHCP servers, and DHCP relay agents on a system. The clients communicate with servers using DHCP messages in a DHCP conversation to receive and renew IP address leases.

Which One Is Better? (DHCP or Static IP)

Proper IP is vital for establishing communications. Which is better?

While DHCP is a protocol as automating the responsibility of assigning static IP addresses allow network devices to keep the same IP address all the time. A network administrator must keep track of every statically apparatus that is assigned. If you use it since configurations are required by IP address, it may create network problems.

As it eliminates the task of assigning IP addresses using DHCP is advantageous for network administrators. It may have a moment, but it becomes annoying when you're currently configuring hundreds of network devices. So that administrators wouldn't have to set their devices by 18, wireless access points use DHCP. For access points, PoE network switches, which support dynamic by users definition are utilized to allocate IP addresses. What makes DHCP attractive is that it's less expensive than static IP addresses with maintenance.

Conclusion

After assessing DHCP vs static IP, it's definitely that DHCP is the more popular, alternative for most users as they're more comfortable and more affordable to deploy. Guessing which IP address can obtain and Using a static IP is time-consuming and bothersome, mainly. Static IP is in helpful and demand if you use a remote access application. Or if you host a website have a file server in your network. Because a static IP address never changes so that devices can know how to get in touch with a system that uses a static IP.
