Useful Tools for Server Administrators – DNS Tools
As we all are aware, web hosting solutions such as the dedicated servers, cloud hosting servers and VPS’s offer root access to the server hence the ability to do almost everything viz. right from its maintenance to configuration settings. A number of administrators encounter issues that may sometimes seem to be beyond control but with the right tools, one can try to figure out the issues and get to the root of the problem. Amongst the wide spectrum of tools used by server admins are the DNS tools that usually come-in handy with finding a basic information about the DNS of a particular server which may offer useful information for troubleshooting the server.
IP / Domain Traceroute – It basically is a computer network diagnostic tool that gives an information about the route (path) and judging the transit delay of packets across an Internet. It offers the ability of tracing the of a computer trying to connect to your server. At-times due to certain network issues related to Internet congestion or similar issues between the source and destination can be judged by using this tool. It provides a list of all the routers it passes through until the destination is reached or fails beyond a certain computer. Moreover, it gives the information about the length of each ‘hop’ from router to router.
Traceroute is enabled on most operating systems.

IP Whois – Also pronounced as Who is, this tool is more often used to know information about the IP address of a particular domain, its location and the details about the registrar and owner. It basically is a query and response protocol used extensively to lookup to databases holding information about registered users of an Internet resource.
Reverse DNS lookup – Also referred to as the rDNS, it is mandatory to have it on your server. It is used for determining the association of a domain name with a particular IP address using the Domain Name System (DNS) of the Internet.
SPAM DB Lookup – This tool enables server administrators to look for the possible accounts on server to be included in the spammers list. Spam DB lookup enables them to check if the server and its IP’s have been added to the list due to a possible spamming activity carried out by someone using the server.
DNS Lookup – DNS lookup is used to determine various DNS records such as A, MX records, CNAME etc. for a particular domain. Using this simple tool, one can check where a particular site is hosted.
