Ping stands for Packet InterNet Groper.
A networking utility - used to test whether a host is alive on an Internet Protocol (IP) network.
Ping sends an ICMP echo request to the target and waits for a reply.
Things it reports:
problems (if there was an error in reaching the host)
Trip time (how long it took to reach the host and come back)
When to use this tool?:
If you are experiencing network difficulties, this is the first tool to pull put of your toolkit.
Tip: if you want to check the name of your host, then ping yourself as ping
ping -a 127.0.0.1.
ipconfig is usually the next tool you will pull out of your toolbox if you're networking a system.
Internet Protocol is a set of rules that govern how data is sent over the Internet or another network.
IP has the function of taking packets from the source host and delivering them to the proper destination host solely based on the IP add in a packet.
With this command you can answer lots of questions:
Which adapters (Ethernet or Wi-Fi or Bluetooth or Virtual network) are connected with an IP address?
Which ones are disconnected?
DHCP is a network management tool. This is the tool that dynamically assigns an IP address to a host on a network. Most likely, a router or a gateway can be used to act as a DHCP server.
Here are two commands for you to use if you want to a new IP address:
ipconfig /release : This releases all IPv4 addresses
ipconfig /renew : This retrieves a new IP address, which may take a few moments
This is a naming system for all hosts that are connected to the internet or your private network. So what you do on the Internet or in a private network, DNS will remember domain names. It will store this data in cache - just to speed up the subsequent requests to the same host.
Note: Cache Poisoning - sometimes called DNS spoofing - is an attack where a malicious party corrupts the DNS case or table, causing the nameserver to return an incorrect IP address and network traffic to be diverted.
Here are two more commands to try:
ipconfig /displaydns: This may scroll for a while because this is a record of all the domain names and their IP addresses you may have visited on a host.
ipconfig /flushdns : if you start encountering HTML 404 error codes, you may need to flush your cache clean. This will force your host to query nameserver for the latest and greatest info.
