Written by

IPv6: [ay-pee-vee-six] noun.

Definition: DDOS

Written by

DDoS: [dee-dahs] noun.

DDoS, short for distributed denial of service, is a type of cyberattack used to overwhelm a website or service to the point that it can no longer perform its intended function. DDoS attacks work by sending a flood of requests to targeted servers in such a high volume that the servers can't keep up with the spike in activity. Programs that launch DDoS attacks are now readily available on the internet, and these attacks have grown in size and frequency in recent years as anyone can launch them with relative ease.

Definition: Ping

Written by


Ping: [piNG] verb.

A computer query to another computer on a network to determine whether there is a connection to it. Ping is a simple tool that's similar to sonar: It allows you to send a signal out to another end point and see if you get a response back. Ping uses ICMP (Internet Control Message Protocol) to send small packets of information to other devices and receive packets in turn. These two functions are referred to as Echo Request and Echo Reply. Unlike SNMP, Ping solely tells you whether a device is online or not and how long it takes to get a response from said device.

Definition: SSL

Written by


SSL: [ess-ess-el] noun.
 

Short for Secure Sockets Layer, SSL is a security protocol that provides data encryption and authentication for data sent over networks such as the internet. It is used to establish a secure connection between a server and a client, like a web server and a browser. It uses two keys to encrypt your data, a public key known to everyone and a private key known only to the recipient of the message. Disappointingly, it does not use socks at any time during the authentication process.

Definition: DNS

Written by


DNS: [dee ehn ess] noun.

The Domain Name System (DNS) is basically the  phone book for any network, the internet in particular. It assigns much easier to remember domain names (like community.spiceworks.com) to their numeric equivalent (like 207.200.22.78). Without DNS, you'd have to remember the IP address of every server you want to visit when you're surfing the internet.

Definition: Subnetting

Written by

Subnetting: [suhb-net-ing] verb.

The act of dividing an IP network into smaller pieces. Subnetting is useful because it can help set up logical network divisions, improve routing efficiency, increase security, and get around some of the limitations of IPv4.

Does not actually involve shoving a sandwich through a basketball hoop.
