Reference Manual for the Model FVS318 Broadband ProSafe VPN Firewall D Denial of Service attack DoS. A hacker attack designed to prevent your computer or network from operating or communicating. DHCP See "Dynamic Host Configuration Protocol." on page 5. DMZ A Demilitarized Zone is used by a company that wants to host its own Internet services without sacrificing unauthorized access to its private network. The DMZ sits between the Internet and an internal network's line of defense, usually some combination of firewalls and bastion hosts. Typically, the DMZ contains devices accessible to Internet traffic, such as Web (HTTP) servers, FTP servers, SMTP (e-mail) servers and DNS servers. DNS Short for Domain Name System (or Service), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned. Domain Name A descriptive name for an address or group of addresses on the Internet. Domain names are of the form of a registered entity name plus one of a number of predefined top level suffixes such as .com, .edu, .uk, etc. For example, in the address mail.NETGEAR.com, mail is a server name and NETGEAR.com is the domain. DoS A hacker attack designed to prevent your computer or network from operating or communicating. DSL Short for digital subscriber line, but is commonly used in reference to the asymmetric version of this technology (ADSL) that allows data to be sent over existing copper telephone lines at data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data (known as the upstream rate). ADSL requires a special ADSL modem. ADSL is growing in popularity as more areas around the world gain access. 4 Glossary M-10146-01

Denial of Service attack
DoS. A hacker attack designed to prevent your computer or network from operating or communicating.
DHCP
See “Dynamic Host Configuration Protocol.” on page 5.
DMZ
A Demilitarized Zone is used by a company that wants to host its own Internet services without sacrificing
unauthorized access to its private network.
The DMZ sits between the Internet and an internal network's line of defense, usually some combination of
firewalls and bastion hosts. Typically, the DMZ contains devices accessible to Internet traffic, such as Web
(HTTP) servers, FTP servers, SMTP (e-mail) servers and DNS servers.
DNS
Short for Domain Name System (or Service), an Internet service that translates domain names into IP
addresses.
Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on
IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the
corresponding IP address. For example, the domain name www.example.com might translate to
198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to
translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.
Domain Name
A descriptive name for an address or group of addresses on the Internet. Domain names are of the form of a
registered entity name plus one of a number of predefined top level suffixes such as .com, .edu, .uk, etc. For
example, in the address mail.NETGEAR.com, mail is a server name and NETGEAR.com is the domain.
DoS
A hacker attack designed to prevent your computer or network from operating or communicating.
DSL
Short for digital subscriber line, but is commonly used in reference to the asymmetric version of this
technology (ADSL) that allows data to be sent over existing copper telephone lines at data rates of from 1.5
to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data
(known as the upstream rate).
ADSL requires a special ADSL modem. ADSL is growing in popularity as more areas around the world
gain access.
