VPN,DNS, and DoH

In the current era when we get blocked access to certain networks, what we do is change the direction of the network by being indirect, or it is called walking further 2x (if your network is standard it will seem long), but usually blocking access itself can be done by the owner or the country where the network is located or even the country where we live. This could be because what we are about to access violates the laws or norms of the country/place where we live. Or if it’s from the country where the network is located, it can be interpreted that the level is quite alarming where our country is on the black list of that country. if that happens then the way we can do is use another method. i.e. using a virtual private network service provider, often abbreviated as VPN extends across a public network and allows users to send and receive data on a shared or public network as if their computing devices were directly connected to Applications running across the virtual private network can take advantage of the functionality, security Encryption is a public part, although not part of the connection. (reference: wikipedia)

However, if it’s only limited to the country where we block certain networks/sites, then we can use other options, because using a VPN there is clearly a hidden risk in it, for example, if we want to access payment networks like paypal, it’s obviously very risky, This applies if the country we are going to blocks our country, because it will change the identity of our network because the VPN will change our IP (Internet Protocol address or abbreviated IP address is a numeric label assigned to each device connected to a computer network that uses the Internet Protocol for communication An IP address has two main functions: host or network interface identification and location addressing (reference wikipedia), so that the provider’s site will take precautions because it does not recognize the ip address with the data it contains. inserted into the network, which can result in money, and in terms of management it is very risky), that’s one example, not to mention the risk of data theft and so on. ALTHOUGH we can use the VPN provided by the company by BUYING, it is still not a guarantee of security. Therefore, if it is only our country that blocks access to certain sites, then we can do simple things, for example we can change DNS, or use DNS over HTTPS.

DNS over HTTPS or often known as DoH is a protocol for Domain Naming System (DNS) resolution using the HTTPS protocol. The purpose of using this method is to protect the privacy and security of users by preventing Man-in-the-middle attacks, and an alternative to DoH is the DNS over TLS (DoT) protocol, a similar standard for encrypting DNS queries, the difference lies in the method used for encryption. and delivery. On the basis of privacy and security, whether or not there is a superior protocol between the two is a matter of debate, while others argue that the merits of both depend on the particular use case (reference : wikipedia )
