IBM Documentation [1]
The configuration options of NSLOOKUP determine the operation and results of your name server queries. These options can be specified in command-mode queries, interactive-mode queries, or in the user_id.NSLOOKUP.ENV data set
If you specify NSLOOKUP options while in interactive mode, the SET subcommand must precede the option. Specifying NSLOOKUP options in the user_id.NSLOOKUP.ENV data set is optional
The (-) operand is not valid preceding options in the user_id.NSLOOKUP.ENV data set.. contains only NSLOOKUP options and defines the NSLOOKUP defaults

What Is the Nslookup Command and How Can You Use It to Improve DNS Security?. Nslookup is a command-line tool that helps you perform DNS queries
By using it they can find out data like domain names, IP addresses, the ports in use, and timeout.. Computer OSs like Windows, macOS, and most Linux distributions have it as a built-in tool
They might be more comfortable to use since you can do all the checking in a browser. But they might not be as safe as the one you have running on your computer.
How to use nslookup command on Linux and Windows Operating System [3]
How to use nslookup command on Linux and Windows Operating System. It’s a helpful command used to get the information from the DNS Server
Using nslookup commands, we can send a query to the DNS(Domain Name System) and display all the details like IP Address or MX records for the specific domain. We also use the nslookup commands to troubleshoot DNS-related problems.
Interactive mode allows us to display all the information like various hosts and domains and print the list of the hosts in the domain. On the other hand, the non-interactive mode will only allow you to request just a name and information about the host or domain
ping [4]
Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012. Verifies IP-level connectivity to another TCP/IP computer by sending Internet Control Message Protocol (ICMP) echo Request messages
ping is the primary TCP/IP command used to troubleshoot connectivity, reachability, and name resolution. Used without parameters, this command displays Help content.
If pinging the IP address is successful, but pinging the computer name isn’t, you might have a name resolution problem. In this case, make sure the computer name you are specifying can be resolved through the local Hosts file, by using Domain Name System (DNS) queries, or through NetBIOS name resolution techniques.

Identifying Inbound and Outbound Ports using Netstat. Identifying Inbound and Outbound Ports using Netstat
Netstat (Network Statistics) is a utility to help us determine whether or not we have inbound or outbound connections on our computer. The Netstat command line utility allows us to determine what ports (both TCP and UDP ) on our computer are listing.
It will also show us the status of the port, whether it’s actually established, has been disconnected by the remote computer or disconnected locally, and whether or not it has a finish statement.. Let’s take a look at what the Netstat utility can do for us.

nslookup command is a useful tool for investigating domain name propagation issues. It allows users to obtain information regarding domain names and IP addresses from the Domain Name System (DNS) infrastructure
nslookup sends a request to the local domain name system server asking for information from its DNS records. In response, the DNS server returns the IP address or relevant domain information for a specific website or server
MS-DOS and Windows command line nslookup command [7]
Nslookup is an MS-DOS utility that enables a user to look up the IP address of a domain or host on a network. The nslookup command can also perform a reverse lookup using an IP address to find the domain or host associated with that IP address.
Nslookup is an external command that is available for the following Microsoft operating systems as nslookup.exe.. nslookup [-opt …] # interactive mode using default server nslookup [-opt …] – server # interactive mode using ‘server’ nslookup [-opt …] host # only look up ‘host’ using default server nslookup [-opt …] host server # only look up ‘host’ using ‘server’
|NAME||Print info about the host/domain NAME using default server.|. |NAME1 NAME2||Same as the command listed above, but uses NAME2 as the server.|
10 most used Nslookup commands [8]
First, let’s talk about what Nslookup is – it is a small but very powerful network administration command-line software. The Nslookup command is available on many of the popular computer operating systems like Windows, macOS, and Linux distros
You can access such a site full of online network tools and search for the option for nslookup. You can define your query for a specific DNS record, to identify the domain, the port in use, and timeout in seconds
If you want high speed, you must use Anycast DNS services! Check this article about Anycast DNS!. Nslookup command is present on most operating systems like Windows, macOS, and most Linux distributions
Debugging or Troubleshooting the DNS Server [9]
In the Linux operating system, we are having the functionality to use the nslookup utility. The nslookup utility or the tool is used to do the DNS lookups in the Linux environment
It will give the details information in terms of IP address, MX records information, NS server details, etc. There are two different modes to work with nslookup
The author of the nslookup is Internet Systems Consortium, Inc.. – nslookup: We can use the “nslookup” keyword in the syntax or command
Chapter 10 Diagnostics and Tools [10]
This chapter defines tools that may be provided with BIND releases, are generally available or just jolly useful! The tools described either provide specific services or may help in diagnosing problems.. BIND provides a number of tools that are invaluable when testing or diagnosing problems
They have the additional property that they may prolong life by removing the blind panic that ensues after making a trivial edit and reloading BIND only to find that the live system is no longer functional due a parameter error and which always seems to take longer to find when we know that hundred of queries are being rejected because the name server is off-the-air.. rndc is the remote access tool that allows selective reload of zones and to which many dns administrators are addicted
nsupdate is a tool that allows dynamic updating (DDNS) of zone files. Extreme care must be taken when configuring BIND to enable DDNS since you may inadvertently open up your DNS zone files to the world – while this is an extremely friendly, neighborly, thing to do it may not always be wise.
IP Services for OpenVMS [11]
To add a new server and enable the BIND resolver, enter:. TCPIP> SET NAME_SERVICE /SERVER=host /ENABLE /SYSTEM
To specify multiple hosts, list them by request preference. The BIND resolver sends the first lookup request to the first host on the list.
To save your changes to the permanent database, enter SET CONFIGURATION commands. The changes you make with the SET CONFIGURATION commands take effect the next time the software starts up
Kali Linux Tools [12]
The Berkeley Internet Name Domain (BIND 9) implements an Internet domain name server. BIND 9 is the most widely-used name server software on the Internet, and is supported by the Internet Software Consortium, www.isc.org.

[email protected]:~# man arpaname ARPANAME(1) BIND 9 ARPANAME(1) NAME arpaname – translate IP addresses to the corresponding ARPA names SYNOPSIS arpaname {ipaddress …} DESCRIPTION arpaname translates IP addresses (IPv4 and IPv6) to the corresponding IN-ADDR.ARPA or IP6.ARPA names
[email protected]:~# ddns-confgen -h Usage: ddns-confgen [-a alg] [-k keyname] [-q] [-s name | -z zone] -a alg: algorithm (default hmac-sha256) -k keyname: name of the key as it will be used in named.conf -s name: domain name to be updated using the created key -z zone: name of the zone as it will be used in named.conf -q: quiet mode: print the key, with no explanatory text. Import DNSKEY records from external systems so they can be managed
What Is nslookup Command? [13]
Name server lookup (nslookup) is a command-line tool that lets you find the internet protocol (IP) address or domain name system (DNS) record of a specific hostname. This command also allows reverse DNS lookup by inputting the IP addresses of the corresponding domains.
To use this tool, type “nslookup” into a command-line interface (CLI) such as the Command Prompt on Windows or Terminal on Linux and macOS.. In this article, we will discuss what nslookup is, its purpose, its commands, and how you should use it
nslookup is a command-line tool to discover the IP address or DNS record of a specific domain name. It also allows for reverse DNS lookup, letting you find the domain attached to an IP address

DNS Troubleshooting Tools [15]
Knowing the tools that are in your troubleshooting arsenal is important when deciding how to tackle a problem with DNS. You can use several command-line utilities—such as the popular nslookup—to manage your DNS server with DNSCMD
The first step in troubleshooting is to ensure that you have the proper permissions for using the tools (that is, you are a member of the Administrators group or you have been delegated permission to use the tools). If you are using a secondary logon, make sure you specify the proper account
One place you can look for information on the performance of your DNS server is the event logs, and if you have DNS debug logging enabled, you can use it as well. To enable DNS debug logging, right-click on the name of the server, click Properties, and click the Debug Logging tab
