What is IP Addresses Glossary?
This section of the IP Addresses Glossary breaks down fundamental terms related to Internet Protocol addresses. Understanding these building blocks is crucial for anyone working with computers, networks, or the internet. We'll explore core concepts of IP address basics and network terminology to build a solid foundation.
| Vocabulary | Part of Speech | Simple Definition | Example Sentence(s) |
|---|---|---|---|
| IP Address | Noun | A unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. For more details, see the Internet Protocol Wikipedia page. | Every device on the internet has an IP Address to identify it. |
| Static IP Address | Noun Phrase | An IP address that is manually assigned to a device and does not change. | Servers often use a Static IP Address so they are always reachable at the same location. |
| Dynamic IP Address | Noun Phrase | An IP Address that is automatically assigned to a device by a DHCP server and can change over time. | Most home computers receive a Dynamic IP Address from their internet service provider. |
| Public IP Address | Noun Phrase | An IP address that is used to access the internet directly; it's globally unique. | Your router has a Public IP Address that websites see when you browse the internet. |
| Private IP Address | Noun Phrase | An IP address used within a private network (like your home Wi-Fi) and is not internet-routable. | Devices on your home network, like your printer, use a Private IP Address. |
| IPv4 | Noun | Internet Protocol version 4, which uses 32-bit addresses (e.g., 192.168.1.1). | IPv4 is the older addressing system, but it's still widely used. |
| IPv6 | Noun | Internet Protocol version 6, which uses 128-bit addresses, offering a vastly larger address space. | IPv6 was developed to solve the problem of IPv4 address exhaustion. |
| Subnet Mask | Noun | A number that defines a range of IP addresses available within a network. | The Subnet Mask helps devices determine if another IP address is on the same local network or a remote one. |
| Gateway (Default Gateway) | Noun | A network node that serves as an access point to another network, often the internet. | Your router typically acts as the Gateway for your home network to connect to the internet. |
| DNS (Domain Name System) | Noun | A hierarchical system that translates human-readable domain names (like www.example.com) into machine-readable IP addresses. | When you type a website address, DNS looks up the corresponding IP address. |
| DHCP (Dynamic Host Configuration Protocol) | Noun | A network protocol that enables a server to automatically assign an IP address to a computer from a defined range. | DHCP makes it easy to add new devices to a network without manual IP configuration. |
| Localhost | Noun | A hostname that refers to the current device used to access it. It translates to the IP address 127.0.0.1. | Developers often test web applications on Localhost before deploying them. |
| Packet | Noun | A small unit of data transmitted over a network. | Information sent over the internet is broken down into packets. |
| Router | Noun | A networking device that forwards data packets between computer networks. | A Router directs traffic between your local network and the internet. |
| Port Number | Noun | A number used to identify a specific process or application running on a device, often used with an IP address. | Web servers typically use Port Number 80 for HTTP traffic. |
Common Phrases Used
This section focuses on practical expressions and internet protocol definitions you might encounter or need to use when discussing IP addresses. These phrases are common in English for IT settings and understanding their usage will improve your communication. Pay attention to how these phrases are used in context, as this can help avoid pronunciation problems with technical terms.
| Phrase | Usage Explanation | Example Sentence(s) |
|---|---|---|
| What's your IP address? | Used to ask someone for the IP address of their computer or device. | "The IT support technician asked, 'What's your IP address?' so they could troubleshoot my connection." |
| Assign an IP address | Refers to the action of giving an IP address to a device, either manually or automatically. | "The network administrator will assign an IP address to the new server." |
| Configure network settings | The process of setting up a device's network parameters, including its IP address, subnet mask, and gateway. | "You may need to configure network settings manually if DHCP is not working." |
| Resolve an IP address | The process by which DNS translates a domain name into an IP address. | "My computer couldn't resolve an IP address for the website, so I couldn't access it." |
| IP address conflict | Occurs when two devices on the same network are assigned the same IP address. | "An IP address conflict can cause network connectivity issues for one or both devices." |
| Renew IP address lease | When a device using a dynamic IP address requests to extend the period for which it can use its current IP. | "If you're having connection problems, try to renew IP address lease through your network settings." |
| Check IP configuration | The act of viewing the current IP address, subnet mask, gateway, and DNS server settings on a device. | "You can check IP configuration using the 'ipconfig' command in Windows or 'ifconfig' in Linux/macOS." |
