Posted on May 13th, 2010Whenever an individual or a corporate firm registers a domain name, the ICANN (Internet Corporation for Assigned Names and Numbers) ask your domain name registrar for submitting your personal contact information to be added to the WHOIS database.
Once the listing appears in the online directory, the data is publicly available to anybody who wants to check the domain names using any of the WHOIS search tool. There may be a number of third parties who want to check the domain names in the WHOIS database, which includes:
- Individuals who want to check their domain names for expiration dates.
- Registrars may sometimes check the domain names to know whether the ownership has been transferred.
- Authorities may check the various domain names while investigating some criminal activity
Network Solutions, an accredited domain names registrar, must satisfy the requirements set forth by ICANN in the case of WHOIS database. At the same time they must also take effort to completely ensure that customers are feeling comfortable with their personal information visibility in the network.
Reverse DNS look up or reverse DNS resolution (rDNS) is the process of determination of a domain name, which is associated with a particular IP address with the help of DNS (Domain Name System) of the Internet. All the computer networks uses the Domain Name System to identify the IP address which is associated to a given domain name. This method is also called as forward DNS resolution.
Reverse DNS look up is just the inverse process of this, and an IP address is resolved into its corresponding domain name. All the reverse DNS database of the Internet is stored in the ARPA (Address and Routing Parameter Area) which is the top-level domain of the Internet. IPv4 uses the in-addr.arpa domain and the ip6.arpa domain is used for IPv6. The reverse resolution of an IP address is done with the pointer DNS record type (PTR record).
3. ISP Cached DNS Lookup
This tool allows you to look up a DNS record in the DNS servers of many of the popular Internet providers. This allows you see which ones possess cached DNS entries. By this way, will be able to see when major ISPs will detect a DNS change made by you. This test is specially designed and it orders the DNS server for not to adding the DNS record to its own cache, if the entry does not exist on the cache at present. Thus the future look ups will not be spoiled.
4. DNS Timing
The DNS Timing Report will test and allow the user to see how fast their DNS servers respond. The test is done with considering many factors like lame delegations, timeouts, etc. After the test a score, which ranges from an F to an A+ is provided to you.
The test also lists all of the problems that affect the DNS server like slow response, timeouts, etc. DNS timing test is test useful in comparing the performance of two different web hosts that provides DNS service. The test can be also used for DNS Troubleshooting.
Traceroute is a computer network tool which can be used to identify the route taken by various packets across an IP network. Traceroute6, an IPv6 variant, is widely used for this purpose. The traceroute tool is readily available on all Unix-like operating systems.
Variants of the tool with with similar functionality are also commonly available; for example Tracepath used on modern Linux installations and Tracert used on Microsoft Windows operating systems. The Windows NT-based OS also provides a tool called PathPing for the above purpose.
With DNS report you’ll be able to quickly see all problems and vulnerabilities associated with your domain and mail server. Thus DNS report helps in solving Email problems, bringing new server or domain online, debugging the various DNS issues, troubleshooting connectivity issues and helps in real-time view of domain and email health.
Ping is one of the computer network tool which is used to check whether a particular host is accessible across an IP network. The tool can be also used to self test the NIC card of the computer, or can be used as a latency test. The tool operates by sending ICMP “echo request “packets to the target host and by listening for the ICMP” echo response replies.
Ping will measure the round-trip time of the packet and will also records the packet loss. After the operation Ping will print the statistical summary of the response packets received, the mean, minimum, max of the round trip time.
