PeerBlock is an application designed for all those users who intend or need to block access to their computers from outside IPs, preventing them from stealing information, data, etc. It happens that we often don't even know that we are being spied on, and we find that we only find out about it when we run an application of this type, so it is worth trying our luck with it or another similar one.

The main uses of PeerBlock have to do with the fact that it will allow us to block personal computers and IPs from any country, which is a considerable advantage for not doing them one by one. Usually, users will have a list of addresses that cannot connect to their devices, which will almost always be considered the most dangerous.

So, this application proposes that we can be completely protected while using our computer, even when we do not have specific knowledge in the field or we can be considered novices. Of course, thinking that we are talking about a free platform for download that does not charge us a subscription, its security proposal may not be 100% effective, so it is better to take its operation with a pinch of salt.

In particular, we recommend installing a program like PeerBlock for all those users who regularly use P2P networks to send or download all kinds of content. In those cases, by using this application in a complementary way, you will achieve an above-average level of security, which will mean that you will have access to new levels of freedom when selecting files to download.

And what about those IPs that may be dangerous but I don't know about? You can download a list of IPs that could pose a risk to your computer directly from the iblocklist.com website. Of course, it is appreciated that we could be protected against some addresses that have been proven to annoy users, but we would like to be able to download lists from other sites as well.

An advantage in this respect is that you can import these lists and select precisely the type of addresses and IPs you want to block, so you don't have to check them one by one. In this way, you can specifically block addresses that correspond to advertising servers, organizations that detect P2P, are adware or spyware servers, and so on.

You can even save your lists and export them to share them with other members of the application's community, which means that you can also use their lists to avoid problems on your PC. That is to say, it is possible to use the detection of potentially dangerous IPs of others while others use ours.

It is also important to remember, as the PeerBlock developers themselves emphasize, that this application receives constant updates, starting with the release of new versions. The advantage of this has to do with the fact that in this way, we can always be protected by knowing the unique IPs that can be a danger to our PC as long as we download the lists of them.

Regarding the interface of this utility, we can point out that it does not differ too much from the usual Windows system or scanning environment, with all the good things that this implies, but also with the negative issues. Indeed, although the menus are clean and the screen generally, we miss that the design does not play a little for a more current proposal. In short, it passes without more.

Suppose we have to reduce ourselves to the main strengths found in our tests of PeerBlock. In that case, we have to highlight the History that has an integrated calendar and search, a management system of all the IPs we have blocked that will allow us to unblock some eventually, and the import of lists of dangerous IPs. All this, of course, without losing sight of the automatic updates released by its developers.

Undoubtedly, PeerBlock also has some elements that we are not too fond of, such as the fact that the lists of potentially dangerous IPs can be obtained from a single source. Also, running this program may prevent us from enjoying some of our favorite games. Finally, there are comments in forums and social networks that denounce that this is not an application that offers reliable protection beyond the fact that we have not had any problems with it.

In short, PeerBlock is a good alternative if you want to keep yourself completely protected from all kinds of IPs that you consider dangerous, both those that you have detected yourself and those that you can download from the website offered. And although, as we said, you can't be 100% sure that a dangerous IP won't sneak in, in general terms, it fulfills its function, and you can't ask for more from a free program.
