what if i have four small ip addresses instead of one big overkill one Classless Interdomain Routing is an addressing mechanism that allows for more complexity in address assignment within a network. It uses bits normally assigned to the Network ID in an IPv4 ...

there are a lot of ways to shout at people nodes unicast vs broadcast vs anycast vs multicast Casting Method Who are we yelling at? How? Group Address Unicast One specific node - - Broadcast Everyone in the broadcast domain - ff:ff:ff:ff:ff:ff last IP...

but what if i was special...? Each OS has their own way of setting up a static IP address for their host system using their terminal. *The most universal way to edit IP configurations on Linux distributions is to edit text files containing the configuration v...

packets are complicated kinda maybe somewhat Ethernet only runs at OSI Layer 1 and Layer 2, so it has no idea about logical networking and all the stuff behind that. The Internet Protocol runs in Layer 3, providing logical network addressing and forwarding. IP...

network protocols define the shape of data being transmitted Network protocols have two main parts: addressing and encapsulation. Addressing describes when and where data is sent, and encapsulation handles how that data is packaged for interpretation, comparab...

yelling at nodes but in mandarin a foreign language now Unicast addressing in IPv6 also refers to a single network interface, just like in IPv4. However, IPv6 addressing is scoped, meaning addresses can refer to a portion/region of the network. Global scoping ...

i need them both, but on a single network Most networks run both IPv4 and IPv6 in some or all segments for connectivity and internetworks. This can be works using dualstack hosts, tunneling, or address translation. Dual Stack Dualstack hosts are able to run bo...

what if i had a gps but for packets >:) Most hosts on a network don't have the necessary capabilities on their NICs to perform routing. This is why each network has a device, aptly called a router, to do that job for it. Routing Table Entries Information on ho...

i need multiple gps apps for some reason Dynamic routing protocols implement algorithms that use information about the network's topology and metrics to build packet forwarding routes. When there are multiple paths available, it chooses one over the rest. Info...

how home network routers work Every home has a SOHO router provided by an ISP that links the LAN to the WAN. Physical Layer Functions The router provides Layer 1 functions, such as a set of RJ45 ports for a local cabled network a set of radio antennae for rec...

the International Organization for Standardization came together one day The official documentation for the OSI model can be found here. The OSI model splits the hardware and software functions that enable data transmission between computer systems into seve...

everyone knows the plug, but not everyone else Star Topology is used most commonly in small LAN networks and SOHO networks due to it's simplicity, easy troubleshooting and easy configuration, since all necessary changes can be made at the switch or router. Any...

how big? how wide? where? Network sizes are determined by the number of connected hosts, while it's scope is the size of the area where the hosts share the same network address. There are two main types of networks, LAN Networks and WAN Networks.

physical layout vs logical layout Physical topology refers to the placement of nodes and what type of transmission media connects them to the network. Logical topology refers to the flow of data through the network. Networks that have different physical topolo...

cmd: msg ZCM-33126123 * /w hi! Networks can be defined as a set of nodes and links, where nodes are the devices that can store and share data and the links are the communication protocols and transmission methods. Network Nodes There are two general types of n...

the public internet's basic structure The WAN interface of the SOHO router connects the local network to the public internet via several methods: digital subscriber line cable fiber optics cellular/satellite PSTN Internet Service Providers ISPs are responsib...

everybody is plugged in with everyone else For every node n in the network, the mesh topology requires n2−n2 P2P links (e.g. network of 40 nodes requires 780 links). However, the redundancy can be helpful, since there are multiple routes data packets can take ...

big hub small hub organize by floors internet for all yippie! Main Distribution Frame -> primary network hub for all the network cables in the building, providing internet access to the entire building (should be in a secure room) Intermediate Distribution Fra...
