RE: Interesting new spam technique - getting a lot more popular.
We end up with customers asking for more IPs too. We just add additional subnets to the interface, perhaps they started with a /30 but now need three more IPs, we just add an additional /29 to the interface leaving both blocks. It is not often that anything needs to be explained to the customer other than the correct subnet mask and gateway for the IPs. This makes our configs look like this for each customer vlan: ip address 2.2.2.9 255.255.255.252 ip address 3.3.2.129 255.255.255.224 secondary That being said, I know at least one of our transit customers does hosting exactly how you are describing. Coincidentally, this customer is also one of the customers that asked if we could "give them a class C block." Using this strategy has never been a problem with ARIN for us, in fact I have applied for and received more space at intervals between 6 and 14 months for the last four years without any issue at all.

is it really that hard to make your foudry/extreme/cisco l3 switch vlan and subnet??? Is this a education thing or a laziness thing? Is this perhaps covered in a 'bcp' (not even an official IETF thing, just a hosters bible sort of thing) ?
Simple: Subnets are hard, customers are stupid, and ARIN is not exactly a hosters best friend. When a hosting customer asks for 5 IPs today and 25 IPs tomorrow, it is infinitely easier for the hosting folks to just slap them into /24s and say "ok uhm you are now .69-.94" than to try and explain subnets, cidr, reserving IP space in cidr sized blocks etc to the customer. Hosters are also generally under-equipped in the paperwork and detailed documentation department, so they tend to run their IP allocations into the ground while attempting to explain their need for more space. CIDR allocations are "wasteful" to them, especially when a customer needs to expand from 30 IPs to 35 IPs and crosses a new boundry. Incase you've never seen hoster configs, they generally look a little something like this: ip address 1.1.1.1 255.255.255.0 ip address 1.1.2.1 255.255.255.0 secondary ip address 1.1.3.1 255.255.255.0 secondary ip address 1.1.4.1 255.255.255.0 secondary ip address 1.1.5.1 255.255.255.0 secondary ... Anything else is quite honestly beyond 99% of hosters out there, they're still blissfully calling these things "class c's". I've seen some truly godawful thins configured by hosters, like chains of 3548s all linking back to a single router interface in ways you can't even imagine. If you made it dirt simple for them they would probably be doing something better (I usually point folks who ask to pvlans, then take the opportunity to make a hasty retreat while they are distracted), but otherwise they don't see the benefit in it. Why bother configuring your router better when you can just send your $5/hr monkey over with a redhat cd and have them reinstall, right? :) -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)

Ok, I KNOW I am going to be slapped by a bunch of people here, but.... I often refer to a /24 (anywhere in the space) as a "class C". I also call the thingie on my digital watch an LCD display, the thing that stops breaks from locking the ABS system and the number I type into the ATM machine my PIN number. Oh yeah, my DLT tape drive is connected to a SCSCI interface. Yup, all of the above are technically incorrect (ok, most of them are just redundant), but I do it anyway, and I am going to carry on doing it, so there!

SLAP! Actually, we've recently seen an Internet service RFP requesting Class A addresses because they were "better" than Class Bs! At least they won't be asking for any Class Cs - too low rent for them ! Hmm, I've just realised that we've just been assigned a "Class A" /18, so maybe we can supply the customer "Class A, Number 1 Grade, Premium, Royal Quality IP addresses" after all. -- "Sheep are slow and tasty, and therefore must remain constantly alert." - Bruce Schneier, "Beyond Fear"
