If anyone's wondering, what's the spinning toilet, here's the reference:
god damn it chuck have you heard of firefox
"The Device that your watching me has a private IP adress!"
wow my toaster has an ip adress
dahslane?
Fun fact
My college of IT in Austria has a subject, with a free CCNA course.
oh my god " Po twojej pysznej zupie" in Chuck film XD I'm done 😀 Now i can really proud of my country thats make this song 😀
Must say this guy really loves his toilet. Btw amazing video as always 😀
Very educative and easy to learn. Just one thing to mention, in private IP table there was a mistake in subnet masks (8/12/16 prefix length)
2:26–2:33 So how exactly do you plan to use dashlane with your toilet? You plan to lock your private toilet so nobody can use it 🤣🤣🤣
Mine is not 192.168.1.0 🤔😏
You say that with NAT a single public IP address is more than enough to connect 300 devices, but from your last video you said the subnet limit imposed on the 192.168.X.X range allows a maximum of 253 devices per instance (with reserved and router addresses removed). Does this mean that on private networks you can unilaterally decide to go classless and give yourself a wider mask that unlocks the second from last octet?
3:22 It was one of the band aids, the others being shared hosting where multiple domain names can share the same IP ("Name based Virtual Host"), and the other being carrior grade NAT.
My cell phone ISP actually divide up the local IPs and give my phone a very small network with as little as 4 local IP addresses in my phones network. So one access point can have over 4 million networks, each with 4 IPs. Class A private IP with a subnet mask 255.255.255.252. And the only devices that need to be in that network are the smartphone and the access point. The highest and lowest IP in a network are never asigned to a device.
However there is now a range of IP addresses taken from a public IP range that is specifically reserved for carrier NAT (CGNAT).
12:15 Yes I get a public IPv6 and public IPv4 address on my cell phone. Like I said one cell phone access point can divide the Class A private network into over 4 million networks allowing over 4 million phones to use the same public IPv4 address. That is one of the reasons IPv4 STILL works.
Cant wait for IPv8 guys
For the love of God PLEASE save us from CGNAT
If we have private IP to uniquely identify each device in a local network then why do we have the MCA addresses for the same purpose as well.
Dashlane is a scam. Any modern browser already has all those features
Noob question here. Does my router has an ipv4 private adress that goes to the server of my ISP and they are the one that have a public ip adress?
No I'm not using privete IPs, my ISP gives me how many public IPs I wan't, I have 7 devices hooked up with cable right now and another 11 connected thru a simple wireless switch. No private IPs.
"Oprah will know, that picture is for toilet" -Network Chuck
what a sentence
There wasn't a need for IPv6, just extend the band aide by just adding a town/city wide router between the home routers and the ISP, the new routers would act as a middle ISP
There are enough IPv6 addresses to give every particle in the universe a unique public address without even making a dent.
"You can't have the same cell phone number" lol I think you need to tell boost that
Your passion for smart toilets are unmatched.
would ipv6 reduce traffic latency ? mack faster internet and less hardware req ?
ive just realised, i have a class A public IP address, even though its literally a home network
I have both an ipv4 and ipv6 address
I once successfully hacked a website by scanning through 0 to 255 on the last digit of a ip address (forgot what it's called) for vulnerable open ports on a private network. It worked! 😜
Could anyone explain to me how does MAC address differ from private IP address? I thought of MAC address as a local way for communication whereas IP is a global way for communication, but with private IP addresses, MAC address seems redundant to me.. thanks in advance
ya we got only 4,3 billion ipv4 adress…but we got 360*10^36 ipv6 adress..so ~360 sextillion mor then enought for the nex years
Hey Chuck! Thanks for these videos, you are a great teacher and this is really helping me understand the fundamentals. U rock 🪨🎸😎
2^128 is more than 340 sextillion, so IPv6 has the same number of IP addresses as 79,228,162,514,264,337,593,543,950,336 IPv4s.
Clearly and absolutely wrong. This isn't true.
Hi Chuck, i got a question. Is it a bad idea to configure 193.xxx.xxx.xxx for the intranet instead of using private address for intranet?
"DAHSLANE" 0:57
Anyone else notice 1:40
BRO EVERY VIDEO MAKES ME HAPPY 0:46
I have learned more about IP Addresses from watching 30 minutes of your channel than I have from years of messing with (and troubleshooting) devices at home.
electronic music at the end?
