We rely on NAT for our Internet access and to allow external access to our internal services. In this video, you’ll learn about private IP addresses, port address translation, and port forwarding.

ive been working on getting my A+ and CCENT for the past several months. i have to say, anytime i get stuck on something your videos help me out a lot. Thank you for having this content available. keep up the good work sir!
Robert Newman !`
Someone has already said it but anytime I sink deep into a subject and realize I'm probably looking far too deep into something than whats needed for the exam, your series always helps me get back on track. I'm on track to take my Network+ next month so thank you very much Prof! :)
Amazingly Awkward how did it go? I am studying for mine.
@@StevenSoto I passed! Barely scraped by with about 9 marks above but a pass is a pass! Best advice is to practice practice practice. Examlabs is a good website that has free questions and very worth investigating in an Exam Cram book. The Examlabs and Exam Cram questions will highlight your weak spots.
@@AmazinglyAwkward Congratulations ! How long did you study before testing?
@@MartyPartyZ thank you! I started around late January/Early February and was certified by 18th of July so around 7 months.
Studying for my Network+ thank you so much Professor Messer for all that you do for the I.T community.
I have an A+ cert and will get my Network+ this year largely due to this content. Indeed.
how's it going so far?
@@yuiyui2947 Side tracked, business started to pick-up, I own an MSP, so I'm pushing this out as few months. I look at my stack of notes every few days in shame 😅😅
This series has been very helpful so far, I also like the subtle Diablo 3 reference as well!
Has anyone been successful or can give me their experience in passing the network plus using just professor Messer videos, labs , and his notes and of course the exam objectives. ? I'm taking my own handwritin notes and may purchase some labs to practice on. I'm very grateful for these videos and he makes them bareable , not like a dry lecture. Thanks Professor Messer !
short answer - use multiple sources of content / videos (like these) books, practice exams, memory tables etc etc etc
i feel like the drone footage is the real reward.
Great video. Very helpful.
I'm a little unclear in something . what does the /8,/12,/16 after the subnet mask correlate to . what is that used for? Also, this only relates to private addresses and translating them over the network using NAT correct ? We do something different to determine the subnet of a public ip address right ? Havent got to that video as I'm sure its coming just want to make myself more clear on understanding this video . Thanks !
Those are the CIDR-block notations associated with the subnet mask, and they specify the number of bits of a subnet mask. For example, a /8 is equivalent to a 255.0.0.0 subnet mask.
@@professormesser does this only correlate to private address or does this mean if any ip add. has a CIDR block of /8 it will always have a subnet of 255.0.0.0? Thanks for your reply .
Yes, /8 is always 255.0.0.0.
What are the differences between DMZ and port forwarding?
What I find confusing about the subject of NAT is, does NAT implies that there are less than 4.29 billions routers on earth ? Does that mean that each router as a unique IPv4 address on the internet ?
Yes, each device directly connected to the Internet has a unique IPv4 address.
@@professormesser Thanks a lot for the prompt response and awesome material. 🙏🏾
Question: When 'Ports' are mentioned, are these TCP or UDP ports? As I don't believe the IP layer supports ports??
The port references are specific to TCP and UDP ports, which are commonly associated with IP traffic.
Love your videos
