Glossary of Terms

access level - The protection level of a user/group determines some aspects of what can be done to a machine. At present only network administrators can set access levels higher than 1.

affiliation - The department or center to which the machine belongs. Undergraduate students in residence halls should use the Residential affiliation. All other users should select the organizational unit responsible for the machine .

building abbreviation - The building abbreviation is a short name for the building.

building name - The name is usually the actual name of the building.

building number - The building number is a number assigned to identify a building. This number is different from the number used to identify the building in the address of a building.

CNAME Record - a CNAME record is dns entry that defines an alternate fully qualified hostname that can be used to refer to the primary host.

ddns authorization - This is the DDNS authorization information. If blank, the zone will be assumed NOT-DDNS. Can contain 'key:XXX', where XXX is a TSIG key, and/or a list a IP addresses that can update the zone. The IP addresses can be written as a list of IP addresses or as a range.

dns configuration name - the dns configuration name indicates what type of dns configuration is set up.

dns resource type name - The name of a dns resource type

dns server control - dns server control is either internal or external. Internal control indicates that the dns server is controlled within the campus network. External control indicates that the dns server is controlled by another organization.

dns software version - This is the version of the software on the DNS server.

dns zone name - This is the e-mail address of the host master of the dns zone.

dns zone soa default - This is the default time to live for all records in the dns zone. Same as dns zone soa minimum.

dns zone soa minimum - This is the default time to live for all records in the dns zone.

dns zone soa refresh - This is the number of seconds that the nameservers will cache SOA information. Thus, secondary nameservers will, on average, notice zone changes after this period of time.

dns zone soa retry - If a nameserver is unreachable, hosts will attempt to re-connect after this number of seconds.

dns zone soa serial - This is the current serial number of this zone.

dns zone type - This indicates the type of this zone. Some values are fw-permissible, rv-toplevel and fw-toplevel

dns _zone soa host- This is the hostname of the master server for the dns zone

domain - The domain identifies a machine as a part of some related group of machines. For example, machines in the "res.wpi.net" domain are residence hall machines. The domain, when used with the short name for a machine, forms the fully-qualified hostname for that machine. Most machines should simply be registered in "wpi.edu".

filename DHCP Option - The filename DHCP option provides the host with the location of an additional configuration file. This file is usually obtained by use of the tftp protocol from the DHCP server unless directed otherwise with the next-server DHCP option.

group - A group is way to refer to a collection of people, and to provide all of those people with the same access rights to an object in the database. At present, only administrative users can create and modify groups.

group id - The group id has the format -- (prefix:name). The prefix is always dept and the name is the name of the group.

group name - The group name is generally the name of the department that the group describes.

hardware address - (sometimes called MAC address or ethernet address) All ethernet cards, whether wired or wireless, have a 12-digit hexidecimal number (which means it can contain the letters A through F in addition to numerals) that uniquely identifies it. When you connect your machine to the network, the network uses this number to verify that your machine is registered. For information on how to find your card's hardware address, see Finding Your Hardware Address. An example of a hardware address is 00E02938A48C, sometimes also written as 00:E0:29:38:A4:8C.

hostname - A hostname identifies a machine by a short name and a domain. For example, if the short name for a machine is "mymachine" and it is in the "res.wpi.net" domain, your fully-qualified hostname will be "mymachine.res.wpi.net"

identity - For protections, this is either an unix user ID or a group id.

IP address - An IP address is assigned to your machine when it is connected to the network. This address uniquely identifies your machine from all others on the internet and is used by other computers and network devices to communicate with your machine. IP addresses are comprised of four numbers between 0 and 255, each separated by dots (###.###.###.###). Most WPI IP addresses begin with 130.215.

IP address zone - Included on the Search Machines page, this field is provided for Computing Services' use. Simply leave it blank.

machine - A network-capable device, such as a computer, printer, or other equipment, that is, or is to be, connected to the network.

mode (IP address) - An IP address can be either static or dynamic. If you have a static IP address, your machine will be given the same IP address every time it connects to the network. If you have a dynamic address, your machine will most likely have a different IP address every time it connects to the network or its DHCP lease is renewed.

MX Record - an MX record is dns entry that defines the fully qualified hostname of the host that mail sent to the current host will be handled by.

network - As used in the machine registration system, one of the non-building-specific networks such as Wireless Andrew, or one of the DSL options.

next-server DHCP Option - The next-server DHCP option tells the host which server to retrieve an additional configuration file from. The specific file retrieved can selected using the filename DHCP option.

READ rights - Checking READ rights for a user or group on the protections page for a machine gives them the authorization to view information about a machine.

resource format - The resource format indicates which zones have access to what

rights - The rights that a user or group is given for a machine (READ, WRITE determines what the user or group may do with the record.

room number - The number assigned to a room in order to identify it within a building.

short name - A short name is the first part of a machine's hostname. The short name is usually created by the user when a machine is registered (although the system generates one if the user doesn't specify one). The short name, when used with the domain, forms a fully-qualified hostname.

subnet - A subnet is a way to refer to a logical block of IP addresses. Ultimately, the subnet determines what IP address the machine receives. What subnet a particular machine should be in depends on several factors, such as the physical location of the machine, the physical connection of the machine, and sometimes even the department affiliation of the machine, or even the specific purpose of the machine, in the case of servers and network hardware. When registering a machine, or changing its subnet, the system allows you to choose the new subnet directly, or to receive help in determining the subnet based on the Building or Network the machine is connected to.

subnet abbreviation - A shorter name to identify the subnet.

subnet base address - The base address of a network is the IP address that identifies the subnet. Generally, the last byte (the rightmost number) of the IP address will be a 0 as such -- x.x.x.0

Subnet name - A subnet name identifies a subnet. Usually this name is indicative of which department or building the subnet belongs to.

subnet network mask - The network mask is usually for a class A network, for a class B network and for a class C network. The network mask controls how many addresses the subnet contains. For a class C network, all IP addresses are available for use except for x.x.x.0 and x.x.x.255.

user - A unix user ID that identifies an individual who will be using a machine or who will have access to the machine data in the Network Registration System.

user name - The user name is generally the real name of the user.

userid - The userid of a user is assigned by the network and is unique for each individual user of the network.

WRITE rights - Checking WRITE rights for a user or group on the protections page for a machine gives them the authorization to change information about a machine.
