charsleysa: Renumbering a large network that hasn't utilized most of its ip space should be relatively simple as you just change the masks to utilize the smallest space required.


I can guarantee that in any of these networks, the addresses assigned are not contiguous, and quite possibly not fully documented.  It's no small job.

This is why we can't have nice things, document your stuff people!

 

I do still think IANA and those organizations should have a chat to see how much of those class A assignments they can free up, even if it as a difficult task.

I work at a University with a historical Class B.  Hindsight is a wonderful thing now, but in 1991 when we got the assignment people were not subnetting with thew view to returning a proportion of their allocation 20+ years later.  We do have everything documented but it would still be a huge amount of work and in our case might free up 20,000 IPs.  Which would be a drop in the bucket in the general scheme of things.  I do understand what you are saying and agree it would be great if some of these assignments could be returned, but I don't think it's likely to happen.

Not sure what the difference for orcon is though - basically all DSL/Fibre modems are on permanently.


Majority? Yes. But certainly nowhere near all. There are a lot of people out there who still turn their modems off when they don't want to use the internet.



That's interesting. I was under the impression the vast majority of consumers had no idea what the little box of wires did, and didn't touch it unless told to by tech support. Good on anyone who does this, conserving a limited resource.

Really?  I always turn my router off when it's not in use (i.e. I turn it off every night before going to bed).  I do this not only for security reasons but also to save power.  Just seemed like the logical thing to do, although I can understand that some people might not do this is they have their router somewhere that's awkward to get to or if they have people in the house that might use it in the middle of the night or they have devices that need to do things overnight (downloads, etc).  But none of this applies to me.

Cydewinder: I'm on an old 200GB Genius plan and just got this email from Orcon:

One of the benefits of the old plan was the static IP which is now being taken away and I have to pay $10 a month. I'm not too worried about the cost, just a little annoyed at the service being changed all of a sudden.

I phoned the contact centre to make the change (can't change online because it keeps trying to force me onto either an unlimited plan (no option for static IP) or an 80GB plan (less data)), and the person I spoke to didn't seem to know this email had even gone out and wasn't sure if I could get it on my account. She also couldn't tell me if my IP would stay the same or change when the order goes through.

Just a heads up in case anyone else is in the same situation.


Hi, I also got caught out like this on Orcon but it was when changing from a legacy plan.

I reluctantly signed up to no-ip.com and have actually found them to be very good. It is much easier to remember a plain english address than a IP address. A heap of routers have built in support for no-ip, which negates the need to run any apps on your immobile computers.

No-ip email out special offers every now and then to their free users and I ended up subscribing for one year at a discounted cost of around USD$15. This removed the need to take monthly action to keep my free accounts alive etc and is cheaper than paying ISP's $10 month. The basic subscription gives you a bunch of accounts, so I set my parents PC up on an account to make it easy to sort their PC problems out remotely etc.

BTW, thanks to the Orcon rep for exolaining the technical reason for doing this.

does the genius router support this, I too subscribe to no-ip at $x/year (dont remember the cost but it isnt much) and not having to have their duc installed would be nice. I havent run the duc for ages because my IP hasnt changed and I know Ill get caught out one day once everything is dynamic and I dont happen to have had the duc installed or something.

My Black Genius supports no-ip.  It's hidden away somewhere in the menus.

I stand corrected. I have the white but thought I had checked the black back when I had it. Obviously my memory failed me.

tkr001 is correct, I've just changed to t he white one as the black on kept disconnecting, unfortunately it doesn't have no-ip support so I'm back to relying on the service running on my main pc (has been good enough so far anyway).

So this isn't the first steps toward moving to CGNAT is it?

And guys, there's no such thing as a "class A", "class B", or "class C" network.  The C in CIDR stands for "classless".  They're called a /8, /16, or /24.

I fix stuff!

No plans to move to CGNAT at this stage.

technically Portunus referring to Class B is still valid considering he is talking about 1991. Though classful is out of the window I still understand what people mean when they say it.

Correct, it definitely was a class B when we got it, hence me calling it historical.
