Using IP 4 for Communication Flashcards
This is a fundamental networking protocol used to translate IP addresses (logical addresses) into MAC addresses (physical addresses) within a local network.
ARP (Address Resolution Protocol)
When a device wants to communicate with another device whose IP address it knows but whose MAC address it doesn’t know, it broadcasts an special message containing the IP address of the target of the request to the entire network. What is this special message called?
ARP Request Packet
(Address Resolution Protocol)
Before the ISP can forward a packet for which the sender address was a private address, it must translate the source IPv4 address private address into a public address which is routable over the internet. What is this process called?
Network Address Translation
These are special addresses used by a host to direct traffic to itself.
Loopback address - generally appied as 127.0.0.1
but actually contains all addresses in the
127.0.0.0-127.255.255.255/8 range.
What 4 communications allow for DHCP addresses to be assigned to individual hosts?
- DHCP Discover
- DHCP Offer
- DHCP Request
- DHCP Acknowledgment
What type of network tranmission is utilized when sending out a DHCP Discover?
Broadcast
What information is included in a DHCP Discover broadcast to allow the DHCP server to make DHCP offer to this specific host?
The DHCP Discover has the MAC address of the host included in the broadcast packet.
When the DHCP server makes a DHCP offer, what information is included in that packet?
IP Address, Subnet Mast,
and Default Gateway
When a DHCP offer has been made, how does the host respond?
DHCP Request
Basically this is an acceptance of the offer that was made.
What response does a DHCP server have upon receiving a DHCP request from a host?
DHCP Acknowledgement
A DHCP request is only sent from a host after the DHCP Discover process
What are the addresses available for distribution from a DHCP server called?
DHCP Scope
