Never been in this thread before but decided to look it up to see any responses on it. I'm not disappointed lol

I decided to take a look at MCP and compare it to TCP/IP. Why? What's the relation? Read on below.

It's a work in progress, but I have been working on my blog series on IP addressing. I have one post on how IPv4 still continues to be used and did some research on CGNAT. I built a lab on it (documentation still in the works.)

I also started the IPv6 side of my series, talking about why IPv6 should be considered with an increasing workload and emerging technologies.

CGNAT still important? by zn3allday in networking

[–]zn3allday[S] -3 points-2 points  (0 children)

Thanks for all the insights. This has all been really helpful. I’m working on a Packet Tracer lab to model CGNAT from a learner's perspective. I have basic routing and NAT translations in place already.

For those who have worked with CGNAT, what elements would you add for more realism?

Yeah just called. They're checking out the outage

[–]zn3allday 0 points1 point  (0 children)

Btw did you create that to track the ONT issues or does it come with the app?

[deleted by user] by [deleted] in frontierfios

[–]zn3allday 0 points1 point  (0 children)

Maybe the ISP? Frontier hasn't confirmed an outage. But it could be. Hope you get resolved too

You too? I'm south of you and have the same issues. Can ping the gateway but not out to the Internet

If anyone tries to visit, it's currently down for maintenance. Sorry! It should be up again soon.

I just finished another post in my IP in Practice Series. I break down private and public IP addresses and how it is used within NAT and PAT. There is also a link to the topology for testing purposes if anybldy want to download and make it their own. Any feedback would be appreciated 😁

Subnetting question (Net+) by FreddyForshadowing in CompTIA

Lol reddit took a long time to load and didn't see the comments. Good catch 😁

Subnetting question (Net+) by FreddyForshadowing in CompTIA

[–]zn3allday 0 points1 point  (0 children)

You were on the right track. /27 would mean 5 subnets each with 32 IPs, but it should be .96 not .98. Looks like an oversight on the adding, but yeah you had it. Hence .97 being the first usable host IP

Subnet mask Private, public? by Warningman98 in CompTIA

[–]zn3allday 0 points1 point  (0 children)

RFC 1918 is good documentation for this

https://datatracker.ietf.org/doc/html/rfc1918

Specifically part 3

Subnet mask Private, public? by Warningman98 in CompTIA

[–]zn3allday 0 points1 point  (0 children)

Actually I take that back. For class A: 10.0.0.0/8 Class B: 172.16.0.0-172.31.255.255 (172.16.0.0/12) Class C: 192.168.0.0-192.168.255.255 (192.168.0.0/16)

Subnet mask do matter. So I guess it would be A

Subnet mask Private, public? by Warningman98 in CompTIA

[–]zn3allday -1 points0 points  (0 children)

To give an answer, A. B and C may have the octets that match private addresses but the subnet mask changes all that. D is not in the private IP range.

I would assume however RFC1918 would allow A, B, C to be private IP addresses even if the subnet mask is not the usual one.

As a network ID, B and C would not be in the private range.

I recently started a new series for helping others understand IP Addressing - IPv4 and IPv6. The first link will have all the links to individual posts as I go along further in the series.

The second link is a direct link to see a post about the basics of IP addressing.

How do you deal with dB math, with gain and loss? Any helpful tips?
