This guy is amazing, his knowledge, clear and simple explanation is textbook. He avoids personal interpretation so as not to confuse from the original ideas. Thank you sir!!!
- IBM owns all the IP addresses starting with 9. 9.x.x.x - IP addresses belong to networks not devices attached to those networks, thus an IP address will change with location (different LAN) while the MAC address is never changes - on modern LANs IP addresses are assigned automatically using DHCP - dynamic IP addresses - Static IP address are configured manually on devices and are typically reserved for servers and network devices while dynamic IP addresses are given to clients #review IP datagram and header - ARP used to resolve/discover an unknown hardware address with a known IP address - Core routers only care about the network ID to route to the next hop router while the gateway router looks at the host ID to deliver to correct destination host - computer performs a subnet mask and operation on an IP address and compares the result to it's own network ID to see if that IP is local or remote IGP - used by routers to share information within a single autonomous system AS - collection of networks controlled by one network operator EGP - control exchange of information between independent ASNs
I think I'm going to have to skip over this portion of the cert for the time being. Better yet, I may never finish the cert at all, thanks to this course. It was a good run though and I'm glad to have a window into modern IT requirements.
Yeah, I know the feeling. It's not a Sprint but more of a marathon. I failed net+ and sec+ years ago. I'm back on the course again and THIS time around there's a carrot 🥕 on the stick awaiting me
13:42: "if the very first bit of an IP address is a zero, it belongs to a class A network." That is, if you were able to look at the bits, you'll notice that for a class A network, he first bit is always '0'. You can better understand this by typing the following script in your terminal: $ for octet_value in {1..127}; do binary_value=$(echo "obase=2; $octet_value;" | bc); printf "%08d
This guy doesn't know what he's talking about clearly , that's why he's not able to explain it basically , he speaks like he is just reading the book, I ask you to change this guy, till he started,I understood everything.
This course went from a 5 to 100 instantly when we hit networking 🙃

Well said!
I'm afraid I'm going to have to come back to this at the end of my certification. I can't have this hold me back from progression
Didn't do has hot as I'd like to in school , great course for catch-up.
Best of luck on your learning journey!
- IBM owns all the IP addresses starting with 9. 9.x.x.x
- IP addresses belong to networks not devices attached to those networks, thus an IP address will change with location (different LAN) while the MAC address is never changes
- on modern LANs IP addresses are assigned automatically using DHCP - dynamic IP addresses
- Static IP address are configured manually on devices and are typically reserved for servers and network devices while dynamic IP addresses are given to clients
#review IP datagram and header
- ARP used to resolve/discover an unknown hardware address with a known IP address
- Core routers only care about the network ID to route to the next hop router while the gateway router looks at the host ID to deliver to correct destination host
- computer performs a subnet mask and operation on an IP address and compares the result to it's own network ID to see if that IP is local or remote
IGP - used by routers to share information within a single autonomous system
AS - collection of networks controlled by one network operator
EGP - control exchange of information between independent ASNs
Thanks man

This got me confused, is there another way to understand it? I'm yet to go into programation
Google please also give quiz here.😇😇
This topic is very difficult, I'm not absorbing it at all :(
Same, it's very badly explained and all over the place !
Network layer like crypto, or layer like search engine tor
Why refer bytes in an IP address as octets?
IP address is written in 4 octet which is 32 bytes as a whole.
What is a difference between an octet and a byte ?
A byte (or octet) is a collection of 8 bits.
Basically the same thing
This part of the course is so badly explained it's almost impossible to understand anything. Part 1 was great but this part is horribly made
This cuy clearly doesn’t understand what he is reading in the prompter since he can’t explain it in his own simple terms

Same, it just goes in all directions !
