What are some websites offering a reverse DNS lookup service?
In computer networking, reverse DNS lookup or reverse DNS resolution is the determination of a domain name that is associated with given IP adress using DNS of the internet.
What is the difference between forward lookup zone and reverse lookup zone in DNS?
Forward lookup is name-to-IP address; the reverse lookup is IP address-to-name.
Which DNS zone resolves an ip address to a qualified domain name?
reverse lookup
Which dns zone resolves an ip address to q qualified domain name?
reverse lookup
What is the no ip domain lookup command used for?
Ip domain lookup command used for forward lookup and reverse lookup to be done in router.to resolve name to ip - forward look up and ip to name - reverse look up.. Router is responsiblr for the same hence we configure this cmd in router whereas switch is not responsible for dns lookup hence at the time of switch configuration we disable this cmd with "no ip dns look up".....
What DNS domain record is used to identify domain controllers?
Hi guys my name is KUDRAT ALI the answer is as follows .... DNS Records are.. HOST RECORD: Where Name is mapped to IP, hosted by Forward lookup zone. SRV (service) RECORD: Where has service location record like (port and IP). Hosted by forward lookup zone. PTR (Pointer) RECORD: Where IP is mapped to name.Hosted by reverse lookup zone NS (name server) RECORD: Where DNS servers information and hosted by both frw lookup and reverse lookup zone. SOA (start of authority) : Where updated made and replications made on bases of version numbers are stored hosted by both fwd look up n reverse look up zone..
What do dns servers use to help resolve IP addresses to dns names?
Forward lookup zones
Reverse look up by address?
Let's say you type in the host name, "www.google.com" into your browser. The browser will contact the DNS (Domain Name Server) and ask it for the ip address (192.117.0.1 for example) for www.google.com. This is what's called a forward lookup. The reverse lookup then is when the browser has the ip address but needs to find the host name for that address. So the browser contacts the DNS using the ip address and asks for the host name.

Which types of DNS zone records are listed in the reverse lookup zone file?
n most DNS lookups, clients typically perform a forward lookup, which is a search based on the DNS name of another computer as stored in an address (A) resource record. This type of query expects an IP address as the resource data for the answered response. DNS also provides a reverse lookup process, enabling clients to use a known IP address during a name query and look up a computer name based on its address. A reverse lookup takes the form of a question, such as "Can you tell me the DNS name of the computer that uses the IP address 192.168.1.20?" DNS was not originally designed to support this type of query. One problem for supporting the reverse query process is the difference in how the DNS namespace organizes and indexes names and how IP addresses are assigned. If the only method to answer the previous question was to search in all domains in the DNS namespace, a reverse query would take too long and require too much processing to be useful. To solve this problem, a special domain, the in-addr.arpa domain, was defined in the DNS standards and reserved in the Internet DNS namespace to provide a practical and reliable way to perform reverse queries. To create the reverse namespace, subdomains within the in-addr.arpa domain are formed using the reverse ordering of the numbers in the dotted-decimal notation of IP addresses. This reversed ordering of the domains for each octet value is needed because, unlike DNS names, when IP addresses are read from left to right, they are interpreted in the opposite manner. When an IP address is read from left to right, it is viewed from its most generalized information (an IP network address) in the first part of the address to the more specific information (an IP host address) contained in the last octets. For this reason, the order of IP address octets must be reversed when building the in-addr.arpa domain tree. The IP addresses of the DNS in-addr.arpa tree can be delegated to companies as they are assigned a specific or limited set of IP addresses within the Internet-defined address classes. Finally, the in-addr.arpa domain tree, as built into DNS, requires that an additional resource record (RR) type - the pointer (PTR) RR - be defined. This RR is used to create a mapping in the reverse lookup zone that typically corresponds to a host (A) named RR for the DNS computer name of a host in its forward lookup zone.
Where might one go to seek information on DNS Lookup tests?
Information on DNS Lookup tests can be found directly on the manufacturer websites, or can be acquired by contacting a customer helpline representative for further information.
