But what is an IP address? What is it for? Why should I know?\nDo not worry, here we will tell you everything you need to know about the\nsubject.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">What is an IP address?<\/h1>\n\n\n\n<p>The first thing you should know is what IP means: they are\nthe initials of Internet Protocol, which translated into Spanish we can call it\nas Internet Protocol. In other words, it is the standard system by which the\ninternet works through a process of sending and receiving information.<\/p>\n\n\n\n<p>An IP address is a set of numbers, unique and unrepeatable,\nthat identifies a device with the ability to connect to the internet. It can be\na computer, tablet, cell phone, or even smart devices prepared for IoT\n(Internet of things).<\/p>\n\n\n\n<p>Consider a simpler example to explain what an IP address is:<\/p>\n\n\n\n<p>Imagine that the roads in your city are the Internet, and\nthe vehicles that circulate on them are the devices from which people navigate.<\/p>\n\n\n\n<p>Whatever the means of transport, everyone has a license\nplate, and it is what identifies and differentiates them. In this sense, we\ncould say that the license plate of a vehicle in this example is the IP address\nof your device connected to the Internet.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">What is an IP address for? <\/h1>\n\n\n\n<p>IP addresses are used to identify devices connected to the\nInternet. They also work to place computers and web portals together on a\nnetwork.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">IP address types<\/h1>\n\n\n\n<p>IPs are divided into two types: public and private. These\ncan be used in two ways: dynamic IPs and static IPs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Private IP Address<\/h2>\n\n\n\n<p>This is the set of numbers that are assigned to each\ncomputer that is connected to a private network. For example, the IP address is\ngenerated by connecting your cell phone, tablet or computer to your home&#8217;s\nWi-Fi network.<\/p>\n\n\n\n<p>On the other hand, private IP addresses are classified into\nthree ranges of number sets. These are the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Class A<\/strong>: From 10.0.0.0 to 10.255.255.255. This is generally used for large networks, such as that of a transnational company;<\/li><li><strong>Class B<\/strong>: From 172.16.0.0 to 172.31.255.255. For medium-sized networks, such as that of a local company or school;<\/li><li><strong>Class C<\/strong>: From 192.168.0.0 to 192.168.255.255. It corresponds to smaller networks, such as home networks.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Public IP Address<\/h2>\n\n\n\n<p>These are visible to anyone who surfs the Internet and\nserves to identify users on the large network. It is intended for servers that\noperate 24 hours a day and it is possible to hire as many as needed.<\/p>\n\n\n\n<p>They are a number that identifies a device within a network\nand an Internet connection point.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Ways to use IP addresses<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">Static<\/h2>\n\n\n\n<p>It is the IP address assigned to a device, which does not\nchange. In other words, it will use the same IP number for life. It applies to\nboth public or private addresses.<\/p>\n\n\n\n<p>Static IP addresses offer greater stability and download\nspeed. Although they may be more vulnerable to certain inconveniences, such as\nhacker attacks for example; Since being static addresses, hackers have more\ntime to operate in them.<\/p>\n\n\n\n<p>To obtain an IP address, it is necessary to pay an\nadditional fee and the configuration of these must be manually, so if you do\nnot have much technical knowledge, it will be necessary to hire someone to help\nyou with the service.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Dynamics<\/h2>\n\n\n\n<p>Dynamic IP addresses are characterized by changing each time\nthe device connects to the Internet. It is generally used when providers have\nmore clients than IP addresses due to the low probability that they all connect\nat the same time.<\/p>\n\n\n\n<p>In addition to offering greater security and privacy, its\nconfiguration is automatic. However, a weak point of this type of IP address is\nthe probability that the connection will be interrupted, as this happens more\nfrequently than in a fixed IP. Many times, when the modem that provides Wifi in\nyour home must be disconnected and connected to improve the connection, your IP\nnumber changed.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">How does an IP address work?<\/h1>\n\n\n\n<p>Now that we have defined what an IP address is, let&#8217;s learn\nhow it works.<\/p>\n\n\n\n<p>The router is responsible for assigning the IPs to the\ndifferent devices that are connected. Thanks to this, it is impossible for two\ncomputers to have the same IP.<\/p>\n\n\n\n<p>For this same reason, it is not possible to maintain fixed\nconnections between several devices, such as shared folders and printers. Since\neach time the equipment is connected, they will have a different IP; This is\nwhat happens with dynamic IPs.<\/p>\n\n\n\n<p>However, we talk about a static IP, as the name implies, we\nwould be talking about an IP address that does not change. This is only\npossible by making a configuration on the device.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">How to find the IP address of a website?<\/h1>\n\n\n\n<p>Finding the IP address of a website or a domain is an easy\ntask. We will show you below the step by step you should follow.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Press the &#8220;Start&#8221; button on your\ncomputer.<\/li><li>Type in the &#8220;cdm&#8221; programs and files\nsearch engine.<\/li><li>Press &#8220;Enter.&#8221;<\/li><li>The MS-DOS console will open, where you must\ntype \u201cnslookup google.com.\u201d Instead of &#8220;google.com,&#8221; you must enter\nthe domain name of the page you wish to consult.<\/li><li>Next, you will see the IP address.<\/li><li>What is the relationship that the IP address has\nwith domains and web servers?<\/li><li>Web pages are created with files, which are\nstored inside a computer that transforms them into the interface that all users\ncan see on the Internet.<\/li><\/ul>\n\n\n\n<p>The computer that stores the information of the websites is\na server, which in turn has one or more IP addresses that identify it, for\nexample, &#8220;74.125.224.72&#8221;.<\/p>\n\n\n\n<p>At the beginning of the internet, computers conversed with\neach other through IP addresses, without using domains or DNS. It is in the\nsame way that someone was calling a friend to a landline. It was necessary to\nknow the number or have it stored in an agenda.<\/p>\n\n\n\n<p>With the rapid massification of the internet and the number\nof websites created, learning or saving the numbers of IP addresses began to be\nan unfeasible activity. Imagine that you had to save the IP addresses of all\nthe websites you enter every day, it would be crazy!<\/p>\n\n\n\n<p>For this reason, the domains were created. They are linked\nto the IP of the server through the DNS (Domains Name System). It simplifies\nthe process of accessing a website. An example of a domain is: mywebsite.com<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">What is the DNS<\/h1>\n\n\n\n<p>The DNS (Domain Name System) is responsible for\n&#8220;translating&#8221; the numbers of an IP address into a domain name. In\nother words, they convert the domain written in the browser and direct access\nto the server to which the domain points.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Where can I find the IP address of the server when buying a Web Hosting?<\/h1>\n\n\n\n<p>Now that you know what an IP address is, what it is for, and\nwhat is its importance in the gigantic world of the internet. It is important\nto keep in mind that when you purchase a web hosting plan to host your website,\nyou receive the information about the IP address that corresponds to the server\nthat will save the information on your website. You must associate it with the\ndomain name you have registered.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>IP addresses are great protagonists of the current operation of the internet.
