I had briefly talked to some one else about it, but the proper term
is Provider Independent IP
Space<http://en.wikipedia.org/wiki/Provider-independent_address_space>.


As that wikipedia entry alludes, ISPs tend not to like this approach.
I used to manage a set of 5 /24s (old style class C nets) which were
independently owned. Moving them between ISPs blows holes in
contiguous address space routing - this tend to make the ISPs unhappy
because of the additional management overhead.

eh say what?

while this would be an issue if you take provider-allocated (also PA) space "somewhere else", this definately is not the case with PI space, as those are completely seperate from the address space "owned" by the provider, and furthermore, they should not have put other customers in it anyway, as PI space "owned" by the customer. (therefore there are no "gaps" in the address space as the entire chunk moves wherever the customer goes and the ISP should have no reason to split it up as it's just that single customer anyway)

nope, the only reason for -some- old jerks to have problems with this is that they run their routing on dusty old cisco shit with just a few megabytes of ram, therefore, it won't fit if a lot of people start to announce a lot of smaller networks, but actually, that's just their problem... (all our routers have 4-128GB of ram, fuck it ;)
upgrades people upgrades..

the thing that DOES NOT make ISPs (or rather: LIRs) happy tho
is the pile of paperwork to fill out to register NEW PI space for customers, as that's a pain in the butt

if the customer ALREADY HAS PI SPACE, we don't care and simply will announce it for the customer, no questions asked.

and one again, if your isp still considers the 'size of the routing table' an issue, its time you find yourself an isp that does not run on routers they bought in 1993 ;)

let's just put it this way: some people are running their network on stuff that has less memory and less packets per second throughput than my GSM, and still think their arguements for not routing smaller networks, including the ones smaller than a /24, will be taken serious by the rest of the internet... :P






Tor nodes seem to be having an issue with DMCA notifications pissing
off hosting providers. Thus we have to either host the nodes with more
"understanding" hosts or limit our exit policies so that we limit the
notifications. This is a problem because the more leniet hosts don't
all ways have the resources or connections that other places have.
If tor nodes controlled their own IP space then they can host their
nodes inside any data center and easier to host without worrying
about DMCA notices shutting down nodes. It would also allow more
liberal exit policies so that other types of traffic can be allowed,
even if they are more likely to generate notifications.


The only problem is that if it is described as tor only, then it
might be easier to block by various groups. Anyone have any thoughts?


It is alreday pretty easy to block Tor activity if you choose. The
project publishes lists of all exit nodes and even offers a DNSrbl list
to those who may wish to use it.
