Nslookup is a command-line utility that is used to send a query to DNS servers to resolve a specific host name to an IP address.
A manufacturing company subscribes to certain hosted services from its ISP. The services that are required include hosted world wide web, file transfer, and e-mail.
Subsequently, question is, what message type is used by an http client? The HTTP message type used by the client to request data from the web server is the GET message.
Secondly, why would you use nslookup?
nslookup is a network administration command-line tool available for many computer operating systems. The main use of nslookup is for troubleshooting DNS related problems. Nslookup can be use in interactive and non-interactive mode.
How does nslookup work?
nslookup is a simple but very practical command-line tool, which is principally used to find the IP address that corresponds to a host, or the domain name that corresponds to an IP address (a process called “Reverse DNS Lookup”). The name nslookup stands for “name server look up.”
What is the function of the Nslookup utility Chapter 10?
What is the function of the Nslookup utility? Explanation: Nslookup is a command-line utility that is used to send a query to DNS servers to resolve a specific host name to an IP address.
Which two tasks can be performed by a local DNS server?
Explanation: Two important functions of DNS are to (1) provide IP addresses for domain names such as www.cisco.com, and (2) forward requests that cannot be resolved to other servers in order to provide domain name to IP address translation. DHCP provides IP addressing information to local devices.
Which is the most popular network service?
At what layer of the OSI model are port numbers addressed?
The Ports are defined in the 5th layer of the OSI model which establishes and controls the dialogue between the source and destination. Port definition is done in the diaogue establishment process. In the TCP/IP model, Layers 5,6 and 7 of the OSI model are included into one Layer (Layer 4 of the TCP/IP model).
Which protocol is used by a client to communicate securely with a Web server?
HTTP is based on the TCP/IP protocols, and is used commonly on the Internet for transmitting web-pages from servers to browsers. The client and server are the end systems also known as Hosts. The Client initiates contact with the server to request for a service.
Which two protocols are used in the process of sending and receiving emails choose two?
IMAP and POP3 are the two most commonly used Internet mail protocols for retrieving emails. Both protocols are supported by all modern email clients and web servers. While the POP3 protocol assumes that your email is being accessed only from one application, IMAP allows simultaneous access by multiple clients.
Which applications or services allow hosts to act as client and server at the same time?
Which applications or services allow hosts to act as client and server at the same time? Explanation: P2P applications allow the clients to behave as servers if needed. When using authentication services, email exchange, and client/server applications, one host acts as server and the other acts as client at all times.
What is an advantage for small organizations of adopting IMAP?
What is an advantage for small organizations of adopting IMAP instead of POP? Messages are kept in the mail servers until they are manually deleted from the email client. When the user connects to a POP server, copies of the messages are kept in the mail server for a short time, but IMAP keeps them for a long time.
What information does nslookup provide?
nslookup is a network administration command-line tool available in many computer operating systems for querying the Domain Name System (DNS) to obtain domain name or IP address mapping, or other DNS records. The name “nslookup” means “name server lookup”.
How do I reverse lookup my IP address?
The Reverse DNS Lookup Tool requires you to enter the IP address that has a corresponding host name. By entering the IP address into the Reverse DNS Lookup Tool, you are able to find the domain name associated with the corresponding IP. For example, one IP address of Google.com is 74.125. 142.147.
What is meant by DNS lookup?
A DNS lookup, in a general sense, is the process by which a DNS record is returned from a DNS server. Interconnected computers, servers and smart phones need to know how to translate the email addresses and domain names people use into meaningful numerical addresses. A DNS lookup performs this function.
How do I find a hostname from an IP address?
Type “nslookup %ipaddress%” in the black box that appears on the screen, substituting %ipaddress% with the IP address for which you want to find the hostname. Find the line labeled “Name” underneath the line with the IP address you entered and record the value next to “Name” as the hostname of the computer.
How do I do a DNS lookup?
Troubleshooting DNS with command-line tools Open a DOS command window. To do this, click Start, click Run, type cmd, and then press Enter. At the command prompt, type the following command. Replace example.com with the domain that you want to test: nslookup example.com. Interpret the output from nslookup.
What is netstat used for?
In computing, netstat (network statistics) is a command-line network utility that displays network connections for Transmission Control Protocol (both incoming and outgoing), routing tables, and a number of network interface (network interface controller or software-defined network interface) and network protocol
