3 Internet Foundation? DNS DNS DEMANDS DOMAIN NAME SYSTEM (DNS) Translates a domain name More People Mobile devices/apps Complex sites Increased latency into an IP address: (IPv4) = 2001:19b8:101:2::f5f5:1d (IPv6) Cloud implementations IPv6 added with IPv4 DDoS attacks WHEN DNS BREAKS EVERYTHING BREAKS F5 Networks, Inc 3

4 Everything: DNS Internet of Things needs scalable DNS services* Combination = 5 to 10 times Internet revolution** 10bil devices in 2014 = 77bil mobile apps** 35% Y/Y DNS query increase*** Ensure really fast connections and responses* DNS Look Ups F5 Networks, Inc 4

5 Demand: DNS AVERAGE DAILY LOAD FOR DNS (.COM/.NET TLDS) QUERIES IN BILLIONS TYPICAL FOR A SINGLE WEB PAGE TO CONSUME 100+ DNS QUERIES FROM ACTIVE CONTENT, ADVERTISING, AND ANALYTICS GLOBAL MOBILE DATA (4G/LTE) IS DRIVING THE NEED FOR FAST, AVAILABLE DNS 18X Growth G LTE Non-4G LTE 2.4GB /mo 86MB /mo DNSSEC DEPLOYMENT EXPANDING SECOND MOST ATTACKED PROTOCOL DISTRIBUTED, AVAILABLE, HIGH- PERFORMANCE GSLB FOR MULTIPLE DATA CENTERS Reflection/amplification DDoS Cache poisoning attacks Drive for DNSSEC adoption Total service availability Geographically dispersed DCs DNS capacity close to subscribers F5 Networks, Inc 5

14 Market Pulse Research: Managing DNS Capacity Key Findings Respondents most frequently cite improved application availability and application performance (speed) as highly important benefits of DNS. A majority (63%) report that their organizations DNS volume has increased over the past year. Contributing factors: rollout of new services, applications. Cloud migration and traffic spikes. Most often, organizations manage DNS capacity by adding more servers (53%) and/or adding more bandwidth (36%). Average of 24 DNS servers in use. With regard to current DNS implementations, outages are the top concern (70% highly concerned). Most concerning consequences: loss of productivity and a poor customer experience. Nearly one-third of respondents (29%) report their organizations have experienced DNS outages in the past 12 months. Culprit? One-quarter of these (25%) report a traffic surge. Among those who indicate their organizations are planning to expand DNS services to the cloud, increasing capacity is the most common driver. On-premise DNS primary case over the next year. Use of public cloud DNS slight increase in next 12 months. F5 Networks, Inc 16

15 The Five Takeaways Scalability: In times of high traffic, enterprises DNS servers must be able to handle shifting volumes of traffic. Security: Denial-of-service attacks frequently target IP addresses that cause DNS server outages. Intelligence: To be protective, IT must be proactive. That means being able to pinpoint application or service delivery accuracy, based on location of users, with geolocation services. Manageability: Enterprises need visibility into DNS services across cloud and on-premises networks, in order to ensure uptime and performance. IT also needs to be able to identify unusual activity that may indicate probing for vulnerabilities. Reliability: With more customers accessing corporate web sites, DNS server performance has the potential to impact user experience and employee productivity. Given these trends, DNS servers must be extremely reliable. F5 Networks, Inc 17
