New document : 5 minutes to understand DNS cache poisoning
The DNS (Domain Name System) is a key service of the Internet. It is a giant, hierarchical and distributed directory that associates IP addresses with domain names that are easier to identify, remember and transmit. It is the cornerstone of the Internet, whose infrastructure has flaws by its very conception, making it an ideal target for attacks. On one hand, the DNS service is based on the authoritative DNS, which holds the information, and on the other hand, the resolver DNS, which ca... Read More
New document : 5 minutes to understand the DNS resolution of domain names
Human beings have a very bad memory for number sequences. However, computers and servers communicate with each other by identifying themselves through an IP address, which is a sequence of numbers or a mix of numbers that is very complex to memorize and differentiate.To help people communicate over networks, the Domain Names System (DNS) was invented. This service is a giant Internet directory, hierarchical and distributed worldwide, which associates domain names with IP addresses.When a we... Read More
The importance of reverse DNS
Image source : Jonbonsilver via Pixabay Reverse DNS is often unknown to domain name managers, especially when the names are hosted by major hosting companies. Reverse DNS allows you to resolve from an IP address to an FQDN. This is the exact opposite of the classic use of DNS, which associates domain names to IP addresses. The reverse DNS allows to answer the question: I have an IP address, what is the FQDN related to it? Reverse DNS operates by creating a reverse DNS zone in which DNS PT... Read More
Choosing the right TLD based on DNS performance
Comparative analysis of the famous Top Level Domains (.com, .fr…) The crux of the war for high-visibility websites is the download time. As a natural referencing factor admitted by Google, this download time can be significantly impacted during DNS resolution. If it is necessary to rely on a first-class DNS infrastructure, the choice of the extension associated with a domain name is important. Indeed, not all registries perform equally well in terms of DNS, not to say that some have di... Read More
DNS on Blockchain: the next evolution of domain names?
Image source: TheDigitalArtist via Pixabay Summary The DNS, the Domain Name System, is a service at the heart of how the Internet operates. It is fundamental to the functioning of many services such as websites, mail servers, VoIP telephony and many others. For more than 30 years, many extensions and functionalities have been added to the DNS, which technically translates into an increase in the complexity of the infrastructure. The Blockchain technology could be a considerable evol... Read More

Arpanet, the Internet’s precursor Arpanet is the first data transfer network developed by the Advanced Research Projects Agency (ARPA) which belonged to the U.S. Defense Department. The first Arpanet node was set up at UCLA on August 30, 19... Read More
Attack on the domain name system: the priority is to protect your access
Image source : Geralt via Pixabay Last weekend, the media has widely communicated on the consequences of an unprecedented attack that targeted the domain names. Indeed, during the night of 22-23 February ICANN reported the large-scale attacks on the domain names: it is DNS hijacking.
