Has nothing directly to do with a NIC, as you can still do this test with a generic modem in a system without LAN network hardware or access. Loopback address is a special IP number The loopback interface has no hardware associated with it, and it is not physically connected to a network. The loopback interface allows IT professionals to test IP software without worrying about broken or corrupted drivers or hardware.

Improve this answer. Yeah, but let's say we don't count ancient systems ; If he has a network stack installed required to set machine's IP , he has the loopback interface.
So A and B can't stay on the same If a and B are given AlberT: I'm confused about what you're saying. According to RFC , any address in But not every net stack accomplish the RFC, so is possible to have packets directed to My poit was to undeline that This was my point — drAlberT.

The old style 'B class' networks are being distributed as much smaller subset these days.
Network classes are a thing of the past. That only defines the reserved range for that block. This is entirely dependent on the netmask in use.
People commonly refer to blocks that they have been assigned in these classes as well even if they have broken them down further. Show 6 more comments.
You can ping It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. The entire address block There are RFCs that explain this. The class A network number is assigned the "loopback" function, that is, a datagram sent by a higher level protocol to a network address should loop back inside the host.
No datagram "sent" to a network address should ever appear on any network anywhere. A datagram sent by a higher level protocol to an address anywhere within this block should loop back inside the host. This is ordinarily implemented using only Sign up to join this community.
