[I did my research]

I read the IPv4 and Subnetting chapters in the CCNA prep material. Watched several youtube videos and read through several forums. However, I still have a small issue because different sources use certain terms interchangeably however I want to be certain and confirm my understanding to avoid confusion.

[The Question]

Q1
Is the network address the same as the node address the same as the network id ?

Q2
Is the host address the same as the host id?

for instance: in this ip 184.19.39.34 is 184.19 the network address == the node address == the network id?

is 39.34 the host address == the host id?

Thanks alot guys !

Q1: Basically, yes. You should note though that there are different kinds of network addresses such as IP addresses, subnet addresses/prefixes, or MAC addresses. The exact meaning of each term depends on context.

Q2: If the IP address/mask is 184.19.39.34/16 then 184.19.0.0/16 is the subnet address. 39.34 is the host part of the IP address while 184.19 is the network part. The IP address is split into these parts as indicated by the CIDR value or the network mask (255.255.0.0 for /16).

Note that this split is only relevant for routing and on the last hop, so you don't need to know the mask value of a far IP address.
