I have a question regarding the Network+ course. This is specifically regarding the 11 - IPv4 subnetting videos that Wes walks through practice questions. I will list some examples of the IP's, but you can also reference the videos themselves.
IP: 137.204.63.50/27, IP: 4.105.74.11/16, IP: 11.46.214.52/12
As you see, these are all public IP addresses. My understanding of subnetting is that it is for segmenting private IP addresses for an internal network. So, my question is, if private Class A: 10.0.0.0-10.255.255.255, Class B: 172.16.0.0-172.31.255.255 and Class C: 192.168.0.0-192.168.255.255, are those examples public IP's being used in a private environment or, are those examples of public IP's being subnetted? If they are public IP's being subnetted in a public environment, is being done by an ISP or something?Hopefully the question makes sense. It doesn't matter for the purposes of how the subnetting works, I am just wondering if I am missing a more fundamental concept of either public IP's being used in and internal network or the idea that public IP's are subnetted in a public environment .

We can subnet public IP addresess. The question here then is when do we do it? When we're assigned a block of IP addresses from our own ISP. For example, when ITProTV was first started. We were assigned a block of IP addresses (e.g. /27 = 30 IP address). I subnetted this spaces to provide for ITProTV 14 of these addresses; 6 ip addresses for another tenant in our building and 6 ip addresses for future tenants in our building too. The ISP sees the entire block belonging to us as long as it falls within that /27 boundary. We assigned the ourselves a /28, the active tenant a /29 and reserved the last block of /29 for future tenants too. When provided with this address space, the ISP also asked how we wanted it subnetted and required us to do and report back to them how we did it.
We can subnet our private IP addresses. We may do so for departmental and administrative purposes as well.

Gotcha! So public IP's are subnetted, I did not know this. Thank you for explaining it to me!

@Daniel-Loyer I remember that one. Not too many people mention that hidden gem💎 precursor, but I remember seeing it pop up a lot in the EU area. I'm glad someone's still giving it its props.
Although, I don't think that the CompTIA Strata IT Fundamentals exam was ever available in the States, unfortunately.
And yes, Mike Meyers was THE source in my opinion for many of the CompTIA stuff (in the 2010s or 2000-teens or 201x’s). But now, in the 2️⃣0️⃣2️⃣0️⃣s, he has some stiff competition! 😉

Do you have a discord study group?

...What I said last year, but is/was curious if ITProTV/aciLearning has also such a group.

No we don't. This would require someone to run the group. Right now, we just don't have the time with our current model of recording.

Search on Discord. There's most likely a CompTIA ITF+ group out there. I know Network Chuck has an A+ group. Not positive on Fundamentals. There may even be an official CompTIA Discord channel.
-
Total Seminars (Mike Meyers' channel) has an ITF area.
-
Just adding myself to this group, so I can be apart of it! :)

Hello all your best bet is post questions here. I usually monitor questions that come in and answer here.
-
hi please how can i answer this question. given a scenario apply application installation and configuration concepts? what are the configuration concepts in this case
-
@Sandra-Funka-Abongwa great question, let me see if I can help with a few examples. You may encounter installation or configuration concepts such as:
- What directories can you find installed applications - (Program Files, Program Files (x86))
- What are the install files for the most common operating systems (.exe, .msi, appx, .doc, .docx...for Windows, .deb, .rpm for Linux, apk for Android, .dmg for MacOS...etc)
- What utilities can you use to install applications (msiexe, Programs and Features, Microsoft Store....in Windows, dnf, yum, apt, apt-get in Linux, Google Play in Android, Mac App Store in MacOS...etc)
There are more concepts around application installation and configuration, but hopefully these examples can help!
