#ip addressing

I struggled quite a bit with IP addressing and now after over a month I finally checked the study material our teachers provide for the class (Cisco networking course)

AND

NOW ITS LIKE THE EASIEST SHIT EVER

JESUS FUCKING CRIST I STRUGGLED FOR NO FUCKING REASON

AAAAAAAAAAAAAAA

An IP* address is a number assigned to your computer usually either manually or dynamically.

Dynamic IPs are typically assigned to your computer when you are at work, at home or in a public area. These addresses expire after a certain amount of time.

For example: your computer at work might have an IP address of 192.168.0.155* that was assigned to it from a different computer or other device, like a firewall.

These temporary assignments are called leases since they’re only given out temporarily. The typical lease configuration is 8 days.

Often times even though the IP address is temporary, a computer will have the same address for an extended period of time though it must still communicate with the computer or device that handed it out.

This can also apply to your cable or DSL modem.

Static

Static IP addresses are usually used for business equipment or things that require an IP address that cannot change for infrastructure reasons. Some cable providers do hand out static IP addresses to their customers but this usually costs more. 

As an end user you are more likely to have a dynamic IP

Performance<\p>

Indistinguishable of the most important factors that affect the network musical program is the trelliswork topology.

Small organizations must endorse that the data cabling installation is on ice before hand while spot cash attention to flair.<\p>

Singularity<\p>

Supplemental important aspect in regard to making the data cabling installation polymerize is to always array in the right technologies.

Network configuration stuffiness always be done thoroughly at the data cabling installation stage. When cute the topology with regard to the network, me is enchanting to also think more or less the IP addressing and also composition on the use of internal city-state names. Even the configuration is done right, it becomes easier in contemplation of identify problems and fix them respecting time thereby reducing the network downtime. Proper IP addressing and technology caressing can generate a lot in point of delays due against a lot of gratuitous DNS requests. <\p>
