DNS Management Tools

The Internet can be a daunting place without DNS management tools. A DNS, or domain name system, is about connection. Since the Internet is basically a massive set of connections between computers all across the globe, there needs to be some kind of mapping system to help users find their way around. This mapping system comes in the form of host names and various Internet protocol, or IP, addresses. These names and numbers are linked. Since such systems allow the user to create a host name that is connected to a specific IP address, utilizing a quality dynamic DNS management service is very important. A DNS system allows other Internet users to find specific web sites. The Bible talks about the importance of seeking God. "But if from thence thou shalt seek the LORD thy God, thou shalt find him, if thou seek him with all thy heart and with all thy soul." (Deuteronomy 4:29)

At least two parts make up a domain name, the top level and the subdomain. For example, if a web site is called www.explainthis.com, "com" is the top level domain. Other possible top levels, in addition to .com, which stands for commerce, could include org., which stands for organization, or .net, which stand for network. There can be many subdomains in any domain name, and these are located to the left of the top level, but there is generally a limit of sixty seven characters total, with four usually going to the top level and leaving sixty three characters for the subdomain. Under the umbrella of one host name can be any number of Internet protocol addresses that are linked to that domain. A host name could be something like www.whatsmyname.com while an Internet protocol address would be a series of numbers that range from 0 to 255 and are separated by periods. Each host name is associated with an IP address. For the average person, understanding how a dynamic DNS management service functions can be confusing. The help of professionals in this area can make all the difference. There are many service providers available that can help the consumer in this area and can provide useful DNS management tools.

Among the services that a dynamic DNS management service might offer could include helping the client choose a domain name and get it registered, aide a client in removing an Internet protocol address from a blacklist, provide customer support, or provide e-mail forwarding and web forwarding. If a consumer simply wants to register a specific name without launching any accompanying web site, these providers can help them do this as well. Other features that these services may offer could include helping clients come up with new aliases and hosts, preventing unwanted web site down time when needed changes are occurring, supplying tutorials and other materials that help the client understand how these systems work, and help a client change web hosting services with minimal complications. Many services also address security issues and will offer spam filtering and keep updated spam blacklists as part of its e-mail forwarding service. One thing to keep in mind when shopping around for businesses that specialize in various DNS management tools is longevity. A potential client needs to know that a business of this nature is going to be in it for the long haul.

For the computer user who is interested in a dynamic DNS management service, there are a wide variety of providers who can help. Dynamic management refers to names that are linked to IP addresses that change. Some computers use Internet protocol addresses that do not change. These are called static Internet protocol addresses. In a dynamic system, these addresses do not remain static, but can change. The reason that this happens is that under a dynamic system, an Internet user is assigned one of a group of unused IP addresses when they log on to the web. That address remains with the user for just one single Internet visit. Providers will generally utilize an application that can dynamically pull unused IP addresses from a pool. Basically, a dynamic service is an extra feature that is added on top of the basic domain name service. The cost of these services may come in the form of a monthly subscription fee that is generally only a few dollars a month.

Other DNS management tools that a consumer might find useful are special software products that can be used to run a system. Some of these applications function as diagnostic utilities. Many programs offer automated features and can go a long way toward saving time and cutting down on human error. Among the features that are offered by this type of software are automated address allocation, policies that are defined by the user, and forecasting and trending for address utilization. The availability of special templates means that configuring the server can be a much simpler process. Additional features could include multi homed hosts, multi tiered addressing, DNS configuration verification, and dynamic capabilities. In the area of address managing, some applications allow the user to define hierarchy according to their own needs such as geography and topology. Automated reporting to regional Internet registries is another helpful feature. If a user wishes to track subnets, IP addresses, resource records or other information, some programs offer audit reporting elements. Whatever needs a consumer might have in this area, there are an abundance of services and applications that can meet those needs and can help take the mystery out of participating in the World Wide Web.

Reverse DNS Lookup

In today's Internet driven world, a good DNS lookup tool can be essential. DNS stand for domain name server. The presumed anonymity that the Internet seems to offer can encourage abuse. The ability to detect the identity of a fellow web user can go a long way in deterring some of these abuses. An IP, or Internet protocol address, is basically a series of numbers that are separated by periods. These numbers are utilized whenever a web user is trying to access a site or send an e-mail. An Internet protocol address look up is basically the ability to translate the name of a web site into these numbers. A reverse DNS lookup goes the other direction. The piece of the puzzle that is missing is not the numbers, but the name. This type of research involves translating numbers into the name of the web address. Look up services that offer the user both forward and reverse capabilities are both numerous and popular on the World Wide Web.

When a computer user is being plagued by excessive span or a suspected hacker, the reverse DNS lookup can help to uncover the identity of the possible offender. These domain names operate on a server and have directories that connect the number with the name. Domain name registries and registrar tables are the sources that enable search services to accomplish these traces. Some lookup services are better than others, but the user can generally find the information that they are looking for, however, it is not uncommon for malicious users to find loopholes that complicate things. There are, of course, many web visitors and e-mail sources that are completely innocent of trying to cause harm to another person's system. These individuals are usually very easy to trace since they are not trying to hide in the first place. Those with malicious intent, such as spammers and hackers, will often go to great lengths to hide their identities and consequently can be a little more difficult to trace for even the best DNS lookup tool. The various disguises that are available for such offenders could include the use of anonymous proxies that hide genuine Internet protocol addresses. Hackers and spammers are skilled at keeping their IP addresses concealed. The Bible talks about the names of the saints that are written down in the book of life. "He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels." (Revelation 3:5)

While the accuracy of a domain name that has been ascertained through a DNS lookup tool can and should sometimes be taken a grain of salt, it may still yield enough information that will allow the user to move forward. The way to determine the name of the particular individual behind a domain name is through something called the Whois database. ICANN, or the Internet Corporation for Assigned Names and Numbers, requires that information about the group or individual who registers a particular domain name be available in the Whois database. Clever offenders may be able to find a way around this and still conceal their identities. But if the search for this information is successful, contact with the individual or group should be possible. The intent behind the Whois database is to make a reverse DNS lookup, or any kind of domain name or Internet protocol tracing, both possible and fruitful. While there may be a variety of reasons that a computer user would need to uncover the domain name of a specific Internet protocol address, system security is certainly one of the motivations. A major benefit of the Whois database is that it can help prevent malicious users from remaining anonymous.

In short, a forward look up involves inquiring about a domain name such as "whoareyou.com." The successful end results of such a search would yield a series of numbers that make up the Internet protocol address. A reverse lookup would begin with an Internet protocol address and hopefully end with the correct domain name, or something like "thereyoouare.com." Other types of searches might include the MX record look up which starts with a domain name and yields the IP address that is attached to the e-mail associated with that domain. A domain name server record look up begins with a domain name and uncovers all of the records that belong to that name.

Since spamming, hacking, and malicious e-mails have become a major problem for Internet users, the DNS lookup tool has become extremely essential. A benefit of this tool has been in the development of anti spam filters and software. By looking at the domain name, this software can often identify and block the most likely sources of spam material. Lists of domain names that can be identified as safe can also help to block many sources of spamming or phishing attacks. A downside to spam filters is that they are not fool proof. It is possible for even the best anti spam or anti phishing software to occasionally block a perfectly safe e-mail. For this reason, many systems will quarantine a suspicious e-mail in a junk e-mail file. The computer owner can check out the source of this suspicious e-mail and opt to delete it if the computer owner is not familiar with or does not trust the source. All in all, the reverse DNS lookup performs a very important function for computer users who are concerned about the security of their system.
