  Anytime a company stores or processes any data that is needed for company operations there should be a contingency plan in place, this plan is a step-by-step plan to keep the company running in a limited fashion even after a disaster. A plan should include at least one supervisor from the different portions of the company to help set a priority list of what services or programs need to be running to do the bare minimum amount of work. Also, a backup plan for communications in the event of a hurricane, flood, tornado, terrorist attack, or zombie apocalypse. Many larger companies already have these and portions of them are shared with the customer within an MOU. Most of the time communication equipment is the top priority followed by intranet sites. To ease the load and better prepare for a failure the use of cloud computing can help keep everything running. Kirvan, P. (2022, May 31). What is a contingency plan? WhatIs.com.

 Ever since computers were created, we tried to connect them from hardwire to Wi-Fi. Most recently we have used the internet protocol version 4, with the limited number of connections IPv4 offers there was a concern that we would run out. To overcome this issue the creation of internal networks was created, basically working by having multiple connections use a single IPv4 external address. Once the separation of networks was created, we specified a network based on what side it is, on the internal side we use IP ranges from 10.x.x.x, 172.16-32.x.x and 192.168.x.x every IP that falls into one of those categories should be specified as an internal IP or a LAN address. On the other side of the network, it is the WAN side. Mumford, A. (2019, July 15). What's the difference between a Lan and a wan? Purple.

When new cables are put in the ground for customers there has been a long-term argument about who covers the last mile of connection. Although this might seem like a silly question it is much deeper than what meets the eyes. When a new building is built and the internet company runs a cable to the house; should the internet company pay more simply because the house if farther back in the lot? This leads to the argument, with companies they might do a 50/50 split with a 3 or 5 year contract with the ISP, for residential there might be a higher install cost or simply not a cable ran.   Additionally, it is costly to put a cable under a road or sidewalk that just add more difficulties for residential internet. In my opinion intent should be a right and each home should be subsidized by the government with the new costly infrastructure bill. Contreras, R. (2022).

  IPv6 has been around for a while, and when it was first created it was for devices that all have an external IP address, with the idea of internal networks by allocating 10.x.x.x and 172.16-31.x.x and 192.168.x.x it enabled the continual use of IPv4. Even larger companies such as Facebook are slowly using IPv6 in the internal network due to the static internal/external IP. The additional thing is that IPv6 will likely not run out, with the number rivaling the amount of grains of silica on earth the end looks to be out of sight. I also like that IPv4 has 4 numbers that are easier to remember if the hostname is not working or DNS goes down. These are temporary work around but if in a production network IPv4 with different ports are much more capable that the integration of IPv6, but that is just my $0.02.   O’Hara, A. (2019, May 30).

DNS is used every day, by almost everyone with an internet connection, it goes unnoticed until it fails. DNS or domain name system was created purely for hour human minds to be able to still access sites without having to remember each IP and port of connections. The way that it works is that “middle” server has a TLD or top-level domain, these are all around us, google.COM usa.GOV are good examples of TLD servers. Each cluster of TLD servers can host multiple sites such as google.com, when connecting to google.com the site will reach out to the google server and return a IP address that the computer can understand, such as 8.8.8.8.  Just think of DNS as a record of each address, a phonebook of sorts. Without DNS the internet could still function but it would be much harder for everyone.

NTFS or the new tech file system is built on the windows platform and utilizing file level encryption NTFS works good with larger files and allows multiple segments to be read at once. NTFS also has features such as maximum file sizes up to 16TB and the use of a complex file structure. All these features as well as logs, and EFS encryption. Compared to FAT it also has built in fault tolerance. With my experience when creating a Windows 10 installation USB it needs to be in either exFAT or NTFS, with my experience NTFS is better even with external HDD and SSD.  Cohen, D. B. (2022, June 1).
