IP Address

(self IP)

Subnet Mask

(mask or netmask)

This mask helps Internet traffic route through networks and subnetworks, and defines the range of addresses that can be used when creating a subnetwork. The format is the same as an IP address, but typically ends with 0:

148.174.0.0.

A device that connects one network to another. This typically involves converting raw data into an IP protocol, or converting one protocol to another protocol.

Acronyms and Abbreviations

ADSL – Asymmetric Digital Subscriber Line is an Internet technology that uses the telephone line to transmit Internet data at broadband speeds. “Asymmetric” means the download speed is faster than the upload speed.

DHCP – Dynamic Host Configuration Protocol is a service that automatically assigns temporary IP addresses to network equipment.

DNS – Domain Name System is a service that converts host names and domain names into IP addresses. For example, a Web URL of www.someplace.com is translated to an IP address such as 140.178.12.56 on the Internet.

FQDN – A Fully Qualified Domain Name is similar to the common Web URL we all use for surfing the Web. Its format typically looks like some.domain.com or just domain.com.

IP (address) – Internet Protocol is commonly used in this document to indicate an address on the Internet. It consists of four numbers separated by periods. For example, 140.178.12.56. Each of these four number must be 0 through 255. Every device on the Internet (including the BSGX4e, computers, and IP phones) has an IP address.

A dynamic address is temporary and is assigned by a DHCP server. A static address is permanent and is manually set in the device.

LAN – A Local Area Network is a technical term for a collection of PCs, IP phones, and other devices that you connect to BSGX4e’s 1–4 ports.

PPP– Point-to-Point Protocol is a popular network protocol for establishing a direct connection between your computer and your service provider. If PPP includes encapsulation schemes, the designation is, for example PPPoE or PPPoHDLC.

PVC – A Permanent Virtual Circuit establishes a permanent, long-term connection directly between your BSGX4e and another network device, such as a switch or server. A PVC has to be ordered from your service provider.
