How to get your connection and your network Data

There are some settings that often need to know to perform certain tasks, like opening ports or mounting servers. I will show you how to obtain them.

Difficulty: Moderate

Instructions

1. 
    
   IP address

   What is IP? An IP address is a code of 4 bytes, separated by periods, which can have values between 0 and 255 (Example: 127.0.0.1). Used to identify a host (computer or server) on a network, either local or extensive.
   
   We must distinguish between IP and Private IP network and IP or public Internet.
   
   The private-IP, has the computer or a network device within it, ie, the code to locate within a local area network.
   
   The IP-service is one that has a computer or network to communicate among themselves and a wide area network (WAN - Internet). This is called a public IP, as when connecting to another host, this address is sent as a parameter so you can reply.
   
   Can the public and private IP the same? If a single computer that does not belong to a network and connect using a modem or router in a Single, the two IP's are equal to each other, as the network information is obtained directly from the device that provides the connection .
   
   If you have a multi-router, or network, these IP's are different.

2. 
    
   public IP address

   How do I find out what my public IP address?
   
   Other methods are to know your public IP address on an IRC client like mIRC, connecting to a server as you show your IP and your Local Host:
   
   [09:35] Local host: B-252-46-ADSL.red.retevision.es (62.175.46.252)
   
   
   In mIRC, you can also use the command / / say $ ip to show to us (always in a status window, because if you do it on a channel, it displays your IP on that channel)
   
   In mIRC options, the connection point - local info, including your public IP address appears when you are connected to a server.
   
   
   How do I get my private IP?
   
   From a very simple way. In the cases described above (not to be networked and have modem or router Single) public IP and private are the same. Otherwise, these are some ways to find out:
   
   Using MS-Dos: Open an MS-DOS window (Start - run - cmd) and run the following command: ipconfig / all
   
   With this command we get enough information, the name of our host, the IP private address of the gateway (the private IP of our router), DNS servers, and the physical address of our network card (MAC)

3. 
    
   router

   Can I have more than one private IP on a single computer?
   
   If you have more than one network card on the same computer, either ethernet or wireless, each network card can have a different IP address configured. If the two had the same private IP were enabled at the same time, errors will occur.
   
   Can you set the private IP? If, in fact it is more advisable, as well as opening the port operations are more reliable. You can also let your router handle automatically send a private IP with DNS and some equipment.
   
   In the configuration of network cards, you can configure these parameters -> Start - Settings - Network Connections -> and right click-properties for the card you want to configure. (They may show local area connection -> ethernet or wireless network connections -> wireless
   
   Select the option Internet Protocol (TCP / IP), the following window

4. 
    
   DHCP server

   If the field set Obtain an IP address automatically and the router' s DHCP server is enabled, the IP is obtained from closed automatically, as is the subnet mask and DNS. This does not always have the same private IP.
   
   
   Manual Configuration
   
   If you configure it manually, you should be as follows:
   
   If the private IP Router (Gateway) is, for example, shown in the image (192.168.0.1) IP network must be within that range, ie the first three bytes have to be equal, the latter can vary between 2 and 255.
   
   The subnet mask must always be 255.255.255.0 and the gateway, the Private IP of the router.
   
   The DNS addresses are the IP addresses of name servers that are going to use. Are provided by your Internet Service Provider.
   
   You know what we are getting the DNS server names. To find out, you just have to run from an MS-DOS window (Start - run - cmd) and enter this command: nslookup.
   
   This command is useful because if you do not find any server to run, it could not navigate even have internet access for services such as Messenger, email, IRC, etc..
   
   It also serves to meet the primary DNS server to use when it is set to obtain DNS addresses automatically.
