Determination of IP addresses. IP address: what is it, find out, check. How to find out your internal IP address.

Who hasn't asked themselves the following questions: What aspects of my computer are visible to others? What areas are available or can be used by others? Are my emails and instant messages from prying eyes? Can anyone watch me surf? The answers to these questions naturally vary depending on the situation for each Internet user. Luckily, there are some general answers. Equipped with some knowledge and well protected, you can set up your own “feel good zone” online step by step.

Step 1: Find out how visible you really are. When you are online, other computer users have access to certain basic information about your computer, since all users are connected via the Internet. The point is that you have to make your computer known to use the Internet. There will be no 100% anonymity when it comes to surfing.

Hackers and other malicious users can scan your ports and find out which ports are open. This is roughly comparable to your phone number or mailing address. This makes you an easy target. It allows you to set up a personal firewall to keep hackers away from your computer and its open ports. At the same time, a personal firewall provides unimpeded access to authorized data traffic to access your computer.

• Ports What exactly is visible?
• Ports are information corridors between your computer and the Internet.
• Each port has a number reserved for a specific function.
• So, for example, Internet traffic is transmitted on port 80.
• Port 25, on the other hand, is reserved for email communications.

For sharing files and printers. Step 3: Keep your surfing habits under lock and key. Their online movements are visible to others to some extent. As you know, your browser records your surfing activities. This feature is useful when you want to return to a recently visited site. Website owners can use this information to gain insight into your surfing habits, especially if you return to their websites frequently.

Fortunately, this problem can be avoided. Your browser can only transmit the address of the page from which access was made when you click on a link. So, if site owners do not know which site you have visited, do not follow the link to that site. Some browsers can also be reconfigured to block referrer forwarding.

Spyware is much more aggressive. They nest on your computer and collect information about your computer habits. You then create a profile of your face and submit it over the Internet to the instance that the program has published. Most spyware enters your computer without your knowledge. However, if you have an anti-virus application installed spyware, you can identify any programs that are trying to access the Internet, including spyware, from your computer.

How to find out your IP address?

Once you have identified the spyware and want to get rid of the spyware again, you can simply uninstall it and relax completely. Step 4: Monitor email and instant messages. Unfortunately, your emails are not secure. From the moment emails leave your computers to their destination, many different people - from mail server hackers to administrators mail servers- It is possible to read your emails.

Likewise, your instant messages are transmitted unsecured over the Internet. They are an ideal attack target for curious people who intercept and read such messages. Also remember to change your email and instant messaging passwords frequently. Although encryption is a bit more expensive, it is still easiest to ensure that only your recipients can read your emails. When it comes to instant messaging, your security is your best defense.

If you have something important to say, save yourself for a more secure communication medium. Step 5: Block viruses and others malware. Some malware can make your system visible to hackers. Some Trojans, for example, place a mechanism on your computer remote control, which provides unhindered access to it. Once a hacker checks your computer, he can use it to attack others, display, control or delete the contents of your computer.

Malware uses various methods to enter your system - email, websites or even floppy disks. Protect yourself from these security breaches by installing a proven antivirus solution. The first bits determine the network class. Depending on the network class, the network portion can range from 7 to 21 bits and is used to identify the network. The user part is used for host discovery and can range from 8 to 24 bits.

As a result, only 256 networks could be solved. In addition, the addressing data differs for different classes. It is characterized by the bit itself High Quality, which is 0. This means that the addresses are in the range from 0 to 255. The network indicator is encoded in 8 bits and 7 bits, respectively, providing 128 different networks.

For this reason, these addresses are intended only for very large users. Address range from 0 to. The number of possible nodes in the network is 16 bits. It is designated by the prefix 110. Addresses of this class range from 0 to 24, respectively. 21-bit network identification theoretically allows for the unique identification of 152 different networks, each with 256 nodes. This class is especially interesting for small companies.

My IP is constantly changing, how can I make sure it is always the same?

Addresses in this category are no longer assigned due to address. The address range varies from 0 to. Using a 28-bit identifier for multicast groups, up to 456 groups can be formed. One identifies a computer on the network. Computers with multiple physical ports have multiple addresses. The address number 0 identifies the network. Addresses in which each bit is set to 1 are reserved for broadcast messages.

The decimal notation shown here, in which individual blocks of addresses are separated by periods, is called dotted decimal notation. Since these numeric Internet addresses have no locational meaning and are also difficult to store, they each agreed on hierarchical alphanumeric Internet names when referring to the address. Internet names are directly related to Internet addresses.

I use a proxy so that it is impossible to find out my IP address, but your service shows my IP, why?

This is a standard that is used to send and receive information through one that collects switched packets. This can result in packages being duplicated, corrupted, out of order, or simply unavailable. If the transmitted packets exceed the maximum allowed in a network fragment, it is divided into smaller packets and reconnected at a certain point.

This means that whoever creates it is responsible for managing the network and does it manually. Secondly, the second form of assignment is an automatic call, which is made in a way that gives it a name and takes as its fundamental basis a range that has already been specified by the above-mentioned administrator.

In the third and last place we have to show that the dynamic path. This means that the direction does not change as hours or days pass. This is achieved by converting the number into four triplets. In this way, better use of directions is achieved.

To obtain a block of Internet addresses, you usually have to request it from your ISP. These organizations typically only serve those requesting very large blocks of addresses. Typically, addresses cannot move from one network to another, meaning if you have an address from one provider, you cannot move it to another.

Differences between internal and external IP

To provide addresses on networks not directly connected to the Internet, some private address blocks are reserved. These addresses can be used by anyone on internal networks, but cannot be forwarded to global Internet. Private address blocks are.

"Protocol" refers to the type of device that computers use to communicate with each other. This is necessary because otherwise it would create a lot of names on the Internet and cause chaos in the traffic, causing messages that we don't need. It also serves to target those who commit crimes on the Internet. We can see that there are three dots, before and after the dots, the value of three numbers from 0 to.

For example: Telephone service X purchases from 000 to. Every web page you visit, on any computer you work on, and even on any routers you connect to, has one of these addresses. It is considered as the name of the communication protocol over the network.

They are therefore a kind of "license plate" to identify you when you are connected. To obtain it there are different ways depending on your operating system, but the easiest way is to refer to the dedicated page to show it to you. There are hundreds and this quick method, which is independent of your operating system.

Well, let's clear these doubts. This will be an internal network configuration consisting of 4 elements: 1 Internet access router, 2 computers and 1 printer. You will see the configuration of all devices or network cards on your computer. You will see the configuration of all network devices. Click "Network" and from the "Configure:" drop-down list select network card which you are using.
