- linux:
1. Open the terminal and enter a `ifconfig ' or `ip addr ' command to obtain the ip information on this machine。
2. The `arm-a ' command may also be used to view the adjacent equipment in the network。
2. Use of web analysis tools
The ip addresses of all the devices in the lan are more easily viewed using a number of dedicated web tools. For example, the use of nmap, a web-scanning tool, allows rapid scanning of specific ip ranges in the following command formats:
````
Nmap - sp 192/168. 1. 0/24
````
The above order will scan all ip addresses in the range of 192. 168. 1. 0 to 192. 168. 1. 255。
Iii. Methodology for finding domain names
The search for domain names takes place in a variety of ways, including using domain name resolution tools or whois queries。
1. Use of command line tools
In the command line environment, we can search the ip address of the domain name by `ns lookup ' or `dig ' command。
- nslookup command:
Supports the use on windows and linux as follows:
````
This post is part of our special coverage global development 2011
````
This command returns information about the ip address and the dns server associated with the domain name。
-dig command:
In linux, the `dig ' command function is stronger, using the following methods:
````
Dig www. Example. Com
````
The command will provide detailed dns information, including a records, suitable for in-depth domain name analysis。
2. Use whois query tool
Whois is a tool for searching for domain name registration information, which provides access to registration, contact information and registration and expiry times. Many websites offer whois queries, which are commonly used by:
1. Whois. Net
2. Icann whois
3. Domaintools
Users need only enter domain names on these platforms to obtain relevant registration information, a feature that is particularly important for station chiefs to understand competitors and confirm domain names。
