Firewire supports multiple protocols. 61883 was one of them.
And you might have seen a 61883.sys or similar at one time.

Networking is one of them.
Typically, a person might use it between two PCs, and using
Internet Connection Sharing.
NIC FW 192.168.1.2
broadband_modem ------ PC#1 --------------- PC#2
ICS Firewire cable
6 to 4 adapter
preferred so no
power is transferred
or power on the connector.
Hopefully, fewer sparks.
The cable still has shield ground, and this may be an
issue if ground potentials are offset.
I don't particularly like connecting Firewires together where
PCs are involved, because the powering strategy might not
be as the standard intended (ground referenced VBUS?). If I
was doing it today, I'd try to use adapters that prevent
VBUS and GND connections, by using 4 pin adapters with only
TX+/TX- RX+/RX- wiring. Using four wire connections to
camcorders is definitely recommended, so nothing gets blown out.
A few people have lost the Firewire port on their $1000 camcorder.

Texas Instruments made a "Firewire box" which
functioned as a hub for Firewire networking. I don't
think anyone bought one. I was never able to find
comments about it, whether sparks came out, or whatever :-)
TI was one of the companies, that attempted to put
capacitive coupling between the MAC and PHY, in an
attempt to avoid a DC path. At one time, people
would state brand preferences for the various
Firewire implementations. Other brands, the MAC and
PHY were one in the same chip, which made it rather
difficult to implement some sort of DC path strategy.
*******
One nice thing about Firewire is RDMA. You can suck the
entire memory contents out of a PC via Firewire. If you're
in the forensics department of the police, this
might allow snapshotting a PC where the perp left
the Firewire port enabled. Who knows what passwords
you might extract, etc.

Certain features of Firewire are disabled in Win10.
I don't think the networking stack is there in Win10.
Not sure what other OSes are hobbled on this.
*******
The only thing you should be using that for today,
is camcorder downloads. Firewire is too much of
a PITA (the stiff cable...) to bother with. It's
from the "vacuum tube era".
