A few years ago, having a fixed IP address was not a strange thing. However, as IPv4 addresses became scarce, operators began to offer dynamic IP addresses by default that changed with each reconnection to assign them more efficiently to users. The fixed IP was left as something optional that users who wanted it could activate, and later it became a paid functionality. Now, all operators charge for it, but not all charge the same.
Having a fixed IP address offers many advantages. Among them, it allows us to have our own server for mail, files or FTP, being able to remotely access our devices, files, or a website that we host ourselves. It is possible to remotely control applications, and video surveillance circuits.
External fixed IP: there are better alternatives
In return, these addresses can be vulnerable to attack, and it is necessary to have greater protection than with a dynamic IP that changes simply by restarting the router. The need for a static IP has been diluted over the years because, although it is more comfortable to perform all these tasks, it is not essential. There is the possibility of using remote desktop programs such as TeamViewer to access computers and use them in turn to control devices in our home remotely. In turn, we can access security cameras through the cloud.
And even if we cannot perform those functions because we do not have a computer on that local network, we can always resort to dynamic DNS services such as no-ip, DynDNS or Duck DNS , which allows us to create a fixed external IP address for free to access our devices. Even if we choose the payment method on that website, the price is $ 24.95 per year, which is practically what it costs a month of fixed IP with an operator. In addition, we can have dozens of hosts and domains to choose from, and we have more privacy because we can put complex names that cannot be known by possible attackers.
Fixed IP price in operators in Spain
In the case of wanting a fixed IP from an operator, most operators usually direct this service to professionals, which is shown, for example, in that the prices that they usually advertise are usually without VAT, in addition to that they may sometimes require to have contracted a business rate. The prices charged by the main operators are as follows:
- Movistar: 30 euros per month
- Vodafone: 18.15 euros per month
- Orange: 14.52 euros per month
- Yoigo: 14.52 euros per month
As we can see, this service is less and less in demand as there are device connections to the cloud and the possibility of hiring dynamic DNS services. In the future, however, all this will change, since when it is decided to finally bet on IPv6, not only will there be a unique IP address for each connection, but we will also be able to have unique external IP addresses for each device and control it remotely and safe.
