Provider networks continue to experience growth in traffic, which raises costs, without corresponding growth in revenues. Accommodating this growth and increasing complexity while managing costs is forcing CSPs to assess how they build and maintain their networks. Everyone agrees everything ultimately resolves to software and fortunately there’s been considerable innovation that will support provider business imperatives.
DNS was first conceived in 1983, back when one of the most memorable movie quotes of all time was popularized: “Go ahead, make my day” (Clint Eastwood in “Sudden Impact”). The internet as we know it today did not yet exist; however, ARPANET, its predecessor network, was the exclusive domain of a small group of academics and researchers, so no one gave much thought to security. A lot has changed.
For many years ISPs in certain parts of the world have been required by their regulators/governments to redirect certain websites that were deemed malicious or suspicious. DNS offered a straightforward way to do this; and Nominum, being a DNS company, developed an early mechanism using a DNS zone file that made it simple for ISPs to comply. The technology was originally named “Malicious Domain Redirection” (MDR), and it basically allowed DNS server operators to perform a single action for a given domain name. Actions could be categorized so that each action or redirection did not have to be repeated.
The term latency is used a lot in networking and most commonly refers to how long it takes a packet to reach a destination and come back again. The most common tools for measuring network latency are ping and traceroute, but there are more. When I speak to operators around Asia Pacific about DNS though, it’s interesting to hear that latency is not often used when benchmarking or measuring their DNS service quality.
The Domain Name System – the DNS – is the foundation of the internet. Beyond connecting IP addresses with web requests, DNS provides the basis for both the detection of and protection from global cyberthreats before they reach an organization’s corporate network resources —particularly given that more than 90% of malware uses DNS for command and control. This presents a tremendous opportunity for service providers to utilize their DNS infrastructure to provide security services to their business customers, which have a tremendous need for stronger, more proactive cyber protection.
Ovum recently published a new report about the digital transformation efforts of communications service providers (CSPs) and the benefits of DNS in enabling a “subscriber-first” approach – a key step to achieving digital transformation. The report, based on the findings of a global survey of 100 CSPs, offers a detailed look at key business and technical priorities and discusses how DNS contributes to optimizing the online subscriber experience and delivering personalized and differentiated services.
The increasingly digital consumer lifestyle, fueled by explosive growth in use of the internet, mobile technologies and social media, has given rise to the empowered customer. With access to more information, choices and opportunities, consumers across all industries are in a position to demand not only what they want, but also where and how they want it.
This story has been told thousands of times before – a botnet is born, a botnet goes down, a botnet tries to get its bots back together. But the story of Necurs is unique.
