Does it ever make sense to use the default
192.168.xxx.xxx to put equipment on?
Using the most popular private subnet in the world
for machines seems to invite many problems and
makes troubleshooting much harder
I was just on project having issues going online with a PLC.
Turns out they were thinking the PLC was alive but were actually pinging something that is not even a PLC a 1/4 mile & 2 buildings away.
(IT is dealing with this as private networks should never be seen public)
I have had problems several times over the years when people
plug things into an incorrect network, do not use a VLAN/NAT,
put the PLC on a the public network
& several other reasons.
192.168.1.xxx is the Rockwell option for Ethernet adaptors
when using the hardware thumbwheel.
I am thinking of using 1.0.0.xxx
Since we have hundreds of PLC's and will have
to type the IP's thousands of times a year
it will save several thousands of keystrokes & typos.
I tried finding articles on often & seldom used subnets but found nothing
Curious what other subnets people use for their machine networks.
Some info I found on private networks:
