What is dynamic IP and what does it do?



What is dynamic IP? Your Internet and network are connected by Internet Protocol (IP) addresses. There are two types of IP addresses: static and dynamic. In this article, we look at the key features of static and dynamic IP addresses so you can make better decisions about how to use them.

What is an IP address?

An IP address is a unique number assigned to each device on a TCP / IP network. Just like the physical address of your home, which allows people to know where to send your packet, it is identified by the IP address of computers and other devices, which allows them to communicate with each other.

Computers, unlike us humans, prefer numbers to names, but for people to access the Internet, the Domain Name System (DNS) is used as an Internet address book. So instead of numbers, you can use words (like www.parspack.com) to surf the web and address devices on your network. These devices can mean anything that connects online. For example: computers, TVs, smart speakers, maybe even refrigerators. Nowadays, almost every electronics in your home can have an IP address.

When you enter a URL in a web browser, DNS is used to search for the domain’s IP address. For example, if you enter www.parspack.com in a browser, DNS returns one of several IP addresses.

IP address versions

Usually two versions of IP addresses are used: IPv4 and IPv6.

IPv4 has four hexadecimal numbers separated by a dot – like: 192.168 ۰ 0.1.1 – while IPv6 has six hexadecimal numbers separated by a dot – like: 2001: 0db8: 85a3: 0000: 0000: 03370. There are approximately 3.4 billion IPv4 addresses, most of which we have used, but there are many IPv6 addresses that will not expire before the end of the universe!

Advantages and disadvantages of dynamic IP

What is dynamic IP? What are the advantages and disadvantages?

What is a dynamic IP address?

As the name suggests, dynamic IP addresses are constantly changing. These addresses are distributed by Dynamic Host Configuration Protocol (DHCP) servers as required.

We use dynamic addresses because IPv4 does not provide enough static IP addresses to assign. So, think of a hotel, it probably has a fixed IP address, but every single device in its rooms will have a dynamic IP address.

Your home or office can obtain a dynamic IP address from a DHCP ISP server. On your home or business network, dynamic IP addresses for your devices — whether computers, smartphones, streaming devices, tablets, or anything else you own — are likely to be assigned by your network router. Dynamic IP is the standard used for consumer equipment.

The difference between fixed (static) and dynamic IP (dynamic)

There is no fixed formula for using an IP address in all people and in all situations. Sometimes it’s better to use a static IP address for your computer or any device, and sometimes a dynamic IP address is a better answer to our needs.

Deciding whether static or dynamic IP addresses are best for you also depends on the nature of the connection. A fixed IP address is more useful for business, while a dynamic IP address may be suitable for a home network.

Advantages of static IP (fixed)

There are many benefits to using a static IP address. These benefits include:

Better DNS support

Fixed IP addresses are much easier to set up and manage with DNS servers.

Server hosting

If you host a web server, email server, or other type of server, having a static IP address makes it easier for customers to find you through DNS. In practice, this means that if customers also have a fixed IP address, they will have faster access to your website and services.

Convenience with remote access

A fixed IP address facilitates remote operation using a virtual private network (IP switching software) or other remote access program.

Safer communication

Static IP addresses make it easier to use Voice over Internet Protocol (VoIP) for teleconferencing or other voice and video communications.

Safer geolocation services

With a fixed IP address, services can map an IP address to its physical location. For example, if you use a local weather service with a fixed IP address, you’ll probably get the weather forecast you need instead of the next city weather report.

Disadvantages of static IP (fixed)

A fixed IP address is not ideal for all situations.

Static IP addresses are more hackable

With a fixed IP address, hackers know exactly where your server is located on the Internet, which makes it easier for them to attack.

A bigger price

ISPs usually charge higher for fixed IP addresses, depending on their application. Their business plans often include a fixed IP, at least as a proposition, but they are more expensive than user plans. Be sure to research the extra costs of your ISP.

Real security concerns

Anyone with the right networking tools can find your location and your computers. Of course, using software to change the IP can reduce this worry by hiding your physical location.

Advantages of dynamic IP

Managing dynamic IP addresses is easier and cheaper than static IP addresses.

Easy and automatic configuration

With a dynamic IP address, the DHCP server automatically assigns the next available IP address to the device and you do not need to do anything special.

Lower costs

You usually save money by using a dynamic IP address.

Unlimited IP addressing

Dynamic URLs allow you to reuse IP addresses. Within a network, your devices are automatically configured with a new dynamic IP address when needed. For example, you always see that when you bring a new computer into your home, you no longer need to manually delete the IP address of the old computer.

You also do not need to assign an IP to the new computer, as the network or router will do this automatically. In fact, when two computers try to use the same IP address, it prevents IP interference.

More network security

With a dynamic IP address, it is more difficult for a potential attacker to target your network equipment. You can also increase your security by hiding your network address with IP change software for your computer.

Better physical security

It is much harder for a spy to know exactly where you are. Using software to change the IP can be a solution to this problem.

Disadvantages of dynamic IP

Dynamic IP addresses are not ideal for all situations. Because they don’t work well for internet services like web or email.

It is unlikely to work well for hosted services

Using a dynamic IP address can be problematic if you plan to host a website, email server, or anything else. DNS does not work well with dynamic IP addresses because the address is always changing. There are Dynamic DNS services that solve this problem. However, they increase the cost and complexity of the network. This can be a serious drawback.

May restrict remote access

Depending on your remote access software, using a dynamic IP address may cause problems connecting to your application. This is where IP change software programs are useful.

More potential damage

Sometimes your ISP will not be able to assign you a dynamic IP address, which is usually not the case, but this can disconnect you from the Internet and is not very annoying for the user, but if your company’s website goes offline, it is very serious. the problem becomes.

geographical location

A dynamic IP address may disable your geolocation services because you can keep the dynamic address from identifying your actual location.

Conclusion

What is dynamic IP? Usually static or static IP addresses can be a great option for companies that host personal websites and internet services. They also work well when remote employees work through IP change software. Dynamic IP addresses, on the other hand, are usually more responsive to most users, are cheaper, and usually have less security risk.

Frequently Asked Questions

1. How do I find my dynamic IP address?

Now that you understand the difference between static and dynamic IP, you may want to know what type of IP you are using and find your IP. One quick way to find out your IP address and type is to use a free online tool like HMA IP Checker.

2. Is it difficult to change the IP address?

If you receive your internet service through an ISP or cable company, in most cases they will assign you a dynamic IP address. Dynamic IP addresses are assigned to your devices on your default network.

Changing a fixed IP address is usually not a problem. You can do this by going to the router’s interface, finding the device to which you want to assign a fixed IP address, and then assigning it (usually by manually entering a number), the details of which vary depending on the router’s brand. On a network with Administrator access, you must ask the system administrator to do this for you.

3. How to protect our dynamic or static IP address?

It doesn’t matter if your Internet IP address is static or dynamic, your ISP and experts can tell you approximately where you are and what you want to do on the Internet. You may want to hide your IP address from spies or anyone else, regardless of type. IP change software can protect your security and privacy in these situations.
