The Domain Name System (DNS) service is required to access e-mail, browse Web sites and use hostnames in general. DNS resolves hostnames to IP addresses and back (e.g. www.cyberguard.com translates to 64.94.50.88). This article details how DNS works under normal circumstances and provides troubleshooting tips. It is important to note that DNS servers essentially comprise a distributed database of hostnames to IP addresses. DNS traffic flow is quite simple. When troubleshooting inbound, be mindful of SOA records and request resolution from the authoritative DNS server. Conduct outbound troubleshooting from the DNS client to the DNS server(s).

Security issues surrounding wireless networking can be addressed without upgrading hardware, Intel said today. The future ubiquity of wireless networking has been a key theme of the IDF this week, with much talk of a mobile computing future where laptop computers automatically select the best connection via either a wireless LAN or high-speed mobile network. This is an attractive vision but there's serious concerns that recently released tools, such as Airsnort, will expose the insecurity of wireless networks, particularly since the security of installed networks has repeatedly been described to us as "flaky". Encryption experts, among them Adi Shamir, the co-inventor of RSA, have highlighted cryptographic weaknesses in the WEP (Wired Equivalent Protocol) security that ships with 802.11b. Best practice calls for the use of virtual private networking techniques to encrypt data flowing over wireless Lans but this is often not followed.
