@gabbytech01 443 is the port for HTTPS

[Cyberfizz @hacktocyberlife]

@gabbytech01 A This is used to get the mac address of a device once you know the ip address of it by sending the broadcast message to it for asking the mac address of a particular ip address

@cyber_razz B prevent switching loops as there could be for eg two switches connected toe ach other and they keep other sending the broadcast traffic to each other with makes them stick in a loop

[Cyberfizz @hacktocyberlife]

@web_stacker B digital signatures as it uses both hashing and encryption and hence if the field is being modified in between the hashing will not provide the correct result leading it to modification and encryption is required so that is cancelled be accessed only by the one with public key

[Cyberfizz @hacktocyberlife]

@CyberRacheal C since It is the Mac address of the device which work at the layer 2 and it is being present on the device which cannot be changed

[Cyberfizz @hacktocyberlife]

@Hamzaonchain B we require 100 hosts so we look in the 4 th octet how many 0s bits are to complete 100 hosts in a LAN. Hence, we use /25 which contain 7 zeros and 2^7=128 which will contain atleast 100 hosts

[Cyberfizz @hacktocyberlife]

@Hamzaonchain C as we use chown change ownership of the file in Linux and first we provide to whom to provide ownership and then name of the file to which ownership is provided

Do you remember when you joined X? I do! #MyXAnniversary

[Cyberfizz @hacktocyberlife]

@cyber_razz B ( since it is /27 hence it will contain3 1s in the forth octet of the subnet of this ip address hence it will have 2^3=8 subnets and 2^5=32 ip address in each subnet so it will contain an ip with 172.16.45.160 as one of the network address which is closest to 172.16.45.190/27

@Ahmed___khaan Not yet
Felt that currently needs to get more better in networking

[Cyberfizz @hacktocyberlife]

@CyberRacheal It checks which of the following IP addresses are allowed to come or else it send it to the demilitrilized zone where if any other device connected locally wants to access a device which is not allowed can be accessed in that particular area
