IPSEC (Internet Protocol Security) is a framework of open standards for ensuring private, secure communications over Internet Protocol (IP) networks through cryptographic security services. It provides essential security features such as authentication, integrity, and confidentiality, making it a crucial component in the establishment of secure virtual private networks (VPNs) and…
In today's digital landscape, the Domain Name System (DNS) plays a critical role in ensuring that internet traffic is properly directed to its intended destination. To improve the speed and reliability of DNS queries, many organizations rely on distributed DNS anycast systems. However, as we learned the hard way, even…
As more and more business-critical applications move to the cloud, ensuring that your network infrastructure can handle the traffic and deliver optimal performance is becoming increasingly important. Linux, being one of the most popular operating systems used for hosting servers, provides several built-in tools to fine-tune the network performance. In…
Border Gateway Protocol (BGP) is a routing protocol that is used to exchange routing information between routers in different autonomous systems (ASes) on the Internet. BGP supports the exchange of both IPv4 and IPv6 prefixes. When BGP is used to exchange IPv6 prefixes, it can be done via an IPv6…
On Linux Servers With IPTABLES Rate limiting is a technique used to control the rate at which network traffic is sent or received. It can be used to prevent network congestion and protect against malicious attacks such as denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks. One way to implement rate…
