Display Software

There have been a couple of times I have seen the displays showing the ip address, presumably because of something not working right. Im going to assume (or more hope) that there is enough security in place which means someone knowing the IP address won't be an issue.

It is most likely the IP address will be in the 10.x.x.x range anyway. These are private IPs that cannot be directly accessed by the internet.

... probably by mac addresses

That's not secure in the slightest, MAC spoofing is pretty trivial.

I would imagine that a system as large as an ATOC one would have an IP address in the class A range, i.e. 10.n.n.n giving over 16 million addresses.

IP subnet classes got phased out in 1993 with the specifying of CIDR

Also 10.0.0.0/8 is specified by RFC1918 for internal use, anyone can use it.

I know that anyone can use it, I have myself at home, (not that I needed 16 million addresses). Many large organisations use the 10.x.x.x group as non-routeable addresses. Where access between sites over the internet network,, either VPN or a local server running an intranet with suitable encription, can give secure access as required.

Although if wired security is vital, it wouldn't be fiendishly difficult to do something like 802.1x

That's just pedantry, surely?

Last time I saw displays starting up (at stations along the Vale of Glamorgan, defenestrating from a diverted Paddington-Swansea HST), they were indeed displaying their IP addresses as being in a 10.x.x.x range. If they'd been displaying public addresses, I might have taken much more of an interest in remembering more than the first octet

That said, the only other time I saw displays starting up was many, many moons ago at Cardiff Queen Street - and they were proudly displaying that IPv4 was disabled, and connection was established via SERIAL!!
