Mmm, the days when organisations used to give printers (!) static IP addresses...and then we ran out of IP addresses and realised that that was a mistake...

That is still standard practice for printers and servers. DHCP for ordinary PCs.

Running out of (local) IP addresses is probably due to assuming that the subnet mask has to be 255.255.255.0, giving 254-ish IP addresses. Lots more can be made available by reducing the third octet, and using one of the other possibilities: 172.16.yyy.zzz or 10.xxx.yyy.zzz

Maybe they wanted someone in another country to be able to print out documents on that printer :rotfl:

The DHSS (as was) has, or had, an entire /8 to themselves :eek:

I think that, back then, no one could predict that also fridges would need an IP address.
By the way, A LOT of those printers are still there with their public IP address, and the worst thing is that they are open on the internet. You can find hundreds of them on Google and you can print anything you like from your computer, apart from seeing what people have been printing.
Which is, obviously, a massive security breach.

I know that wasn't addressed to me, but I certainly remember ...

As a programmer, rather than someone in IT (proper or otherwise), for some reason I'm strangely reluctant to offer much assistance in these topics.

Who said that I had printers with a public address?

I said that, in the past, big organisations and universities were allocated so many IPv4 addresses that also printers were given one (and they still have it!) because they thought that they would never run out of addresses.

Having a public IPv4 address does not mean that it is not behind a firewall .

Then you'd better change your firewall or your IT dept. if your printer can be accessed by anyone on the internet without any hacking and it doesn't even ask for a username and password.
And no, if you assign the address directly to the printer, then there is no firewall in between.
