|DNS server port||
inbound port 53 to accept name resolution requests
|Windows Internet Name Service (WINS)||
a service that resolves NetBIOS names to IP addresses. It is Microsoft’s version of the NetBIOS Name Service (NBNS)
allows client computers to connect to and take control of a server.
|Routing and Remote Access Service (RRAS)||
A network service in Windows Server 2008, Windows Server 2003, and Windows Server 2000. It allows an administrator to configure dial-up remote access servers, VPN servers, and configure IP routing, as well as NAT.
A protocol within the TCP/IP suite that encrypts and authenticates IP packets. It is designed to secure any application traffic because it resides on the network layer.
This is a single address on a single interface.
|global unicast addresses||
routable and displayed directly to the Internet. These addresses start at the 2000 range
|link local address||
two subtypes, the Windows auto-configured address, which starts at either FE80, FE90, FEA0 and FEB0, and the loopback address, which is known as ::1
These are addresses assigned to a group of interfaces, most likely on separate hosts
These addresses are also assigned to a group of interfaces and are also most likely on separate hosts, but packets sent to such an address are delivered to all of the interfaces in the group
|Routing Information Protocol (RIP)||
A dynamic protocol that uses distance-vector routing algorithms to decipher which route to send data packets
|Open Shortest Path First (OSPF)||
A link-state protocol that monitors the network for routers that were turned off, turned on, or restarted
|Interior Gateway Routing Protocol (IGRP)||
A proprietary protocol used in large networks to overcome the limitations of RIP.
|Border Gateway Protocol (BGP)||
A core routing protocol that bases routing decisions on the network path and rules
|Characteristics of X.25||
•It is usually digital.
•It is usually synchronous. This means that the connection is controlled by a clocking circuit so that both X.25 devices know when to transmit data without having collisions.
•It involves a 56K or 64K max line.
•It is also known as variable length packet switching.
•A PAD decides which circuit the information is going to take as part of the virtual circuit concept.
•Packets usually have 128 bytes of actual data, but some configs go up to 512 bytes.
|PSE (packet switching exchange)||
mega switching computers that handle huge numbers of packets and decide which circuit each packet will take
a newer form of packet switching designed for faster connections
