Diagnosing IPv6 in Nanoseconds: RFC 8250
As modern networks scale, the boundary between application performance and network behavior grows blurry. Network performance issues are notoriously hard to pinpoint. A web page loads slowly, but is it the DNS resolution, the server, the network? Often, the tools used to answer these questions are built on guesswork and indirect probes. RFC 8250, however, […]
DNS Key Trap
The DNS Key Trap According to the National Vulnerability Database Certain aspects of DNSSEC in the DNS protocol, outlined in RFCs 4033, 4034, 4035, 6840, and related documents, enable remote attackers to initiate a denial of service (CPU consumption) through multiple DNSSEC responses, known as the “KeyTrap” issue. One significant concern is that when a […]
Implementing DNS Resolver Security
Introduction DNS resolvers are the backbone of internet connectivity, converting human-readable domain names into IP addresses. For Internet Service Providers (ISPs), ensuring the security of their DNS resolvers is crucial to maintaining the trust and safety of their users. This blog explores the importance of DNS resolver security for ISPs, common threats, and best practices […]
Measuring Latency with Ping: Enhancing Network Performance Insights with AIORI
In the realm of network performance, latency is a crucial metric that reflects the time it takes for data to travel from a source to a destination and back. High latency can degrade user experiences, especially in real-time applications like online gaming, video conferencing, and VoIP. One of the simplest yet powerful tools to measure […]
DNS Security: ZONEMD Ensures the Integrity of Entire DNS Zone Files
The Domain Name System (DNS) is a cornerstone of the internet, translating human-readable domain names into IP addresses. Given its critical role, maintaining the integrity and security of DNS zone files is essential. ZONEMD (Zone Digest) is a novel mechanism designed to enhance the security of DNS by ensuring the integrity of entire zone files. […]
The Role of SPF, DKIM, and DMARC Records in Email Security
Email is a fundamental communication tool, but it is also a common vector for spam, phishing, and other malicious activities. To combat these threats, organizations use various email authentication methods. Three critical technologies in this area are SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance). This blog […]
The Internet Measurement Network (AIORI-IMN)
Abstract: This paper establishes the need of an Internet measurement network for India which is capable of measuring, collecting, analysing, collaborating and sharing metrics. The purpose is to help in advanced Internet operations research towards a fast, responsive, stable, resilient and secured Internet infrastructure. The paper using use-case demonstrates the advantages of having an indigenous […]
