• In TCP/IP v.6, older tunneling protocl being replaced by Toredo/ ISATAP protocols
• Tunnels use by IPv6 to transport packets to IPv4 network

• collectv name for IEEE 802.11 standards for local wirelss netwrking
• (techncl name for Wi-Fi)

MAC addrss

standard used by WPA2 & currently strongest encrypt'n standard used by Wi-Fi

when config TCP/IP in Win, addrss Win uses if it can't lease an IP addrss from DHCP server

using TCP/IP v.6 - type of IP addrss used by routers & id's mult destin'ns. Packets delivrd to closest destin'n

TCP/IP v.4, IP adrss in range 169.254.x.y., used by comptr when can't succsfuly lease IP addrs from DNS server

connectless protocl

spec, radio frequency w/in  broader frequency

• license for range of IPv4 IP adrss,defines single octet, is ntwrk port'n of IP addrss in that license.
• last 3 octets used for host addrss/subneting ntwrk

• license for range of IPv4 IP adrss
• defines 1^st 2 octets, used for ntwrk port'n of IP addrss
• last 2 octets used for host addrss/subneting ntwrk

• license for range of IPv4 IP adrss
• defines 1^st 3 octets, used for ntwrk port'n of IP addrss

• TCP/IP v4 subnet mask used if ntwrk not ÷ into subnets
• ntwrk portion of IP addrss aligns w/ class license
• Ex: 11111111.11111111.11111111.00000000 or 255.255.255.0 is classful subnet mask for class C license

• TCP/IP v4 subnet mask takes some bits of host portion of IP addrss for ntwrk ID & doesn't align ntwrkw portion of IP adrss w/ ntwrk octets assigned by class license.
• Can have mix of 1's & 0's in one octet or contain all 1's in octet that wasn't leased by class license
• Ex: 11111111.11111111.11110000.00000000 or 255.255.240.0

host name

• TCP/IP protocol (ex: UDP)
• works @ OSI Transport layer & doen't guarantee delivry by 1^st connectng & checking where data received.
• used: broadcastng (streamng video/ sound over web, where guaranteed deliv not as important as fast transmission)

• in ntwrking, TCP/IP protocl confirms good connect'n made b4 transmittng data to other end
• verifies data received & resends if not
• Ex: TCP

gateway a comptr on ntwrk will use to accss anothr ntwrk unless it knows to specifcally use another gateway for quickr accss to that ntwrk

used by servr to assign a dynamic IP addrss to comptr when 1^st attempts to initiate a connect'n to ntwrk & requests IP addrss

• name I.D.s ntwrk & appears b4 period in website addrss such as microsoft.com
• fully qualified domain name is sometimes loosly called domain name

• IP addrss assigned by DHCP server for current session only, & leased when computr 1^st  connects to a ntwrk.
• once session term, IP addrss returned to list of avail addrss

MAC address

protocl email servr & client use when client requests email msg download

aka: port address/ port #

1.  applied to servc running on computr, # assigned to procss on comptr, so that procss can be found by TCP/IP

2. physcl connectr usually @ back of comptr, allows cable from peripheral device (printer,  mouse/ modem to be attached

• to open/close certain ports so they can/can't be used
• firewalls use to protect ntwrk from unwanted communc'n

techniq allows comptr on internet to reach comptr on private ntwwrk using certain port when private ntwrk protected by firewall device using NAT

when firewall opens port, cuz comptr behind firewall initiates communc'n on anothr port
