This is simply not practical, networks usually have little control over how many ASNs sit between them and networks they want to reach, this is a matter of routing policy. Also, IRR filtering, whilst a wonderful idea, is hugely impractical as a blanket suggestion, mainly down to untidy IRR data and sheer numbers of prefixes involved as you look at some of the larger networks. For instance, I did a brief study of the top 5 peers at the LINX by prefix count recently, unrolling their IRR Macros yielded nearly 330k prefixes Since we all already started developing a secure framework for BGP , I think we should just pick up the pace a little on this, if anything.

Some ideas on how to protect against longer-prefix hijacking
by Tomas L. Byrnes 24 Feb '08

24 Feb '08

Fundamentally, this is a policy issue, and the implementation details will need to be worked out, but today's event with YouTube is an exclamation point on a problem many of us have been wrestling with for some time: the advertising of unused but non-bogon address space by cybercriminals. Whether accidental or not, the black-holing of Youtube by Pakistan Telecom demonstrates a serious weakness in the "longest prefix wins" rule: there is no concept of trust contained in it. Trust, whether implicit or explicit, is inherent in all human interactions, yet expressing it in cyberspace has continued to be troublesome. In routing decisions, once you are beyond a connected (either directly or multi-hop) peer, it becomes much more difficult. I'm going to stay away from the political issues here, because I've been told to, but I think they really need to be weighed. Just as the companies we each work for or run take into account the regulatory framework and rule of law in the jurisdictions in which we do business (and use those as metrics on whether to do business at all in many places), I think it is wise to take those items, as well as other matters that play into trustworthiness, into account when choosing to accept routing information. So, let's start with some observations (I'm very willing to be corrected): Due to history and network geography, the distribution of longer prefixes is not uniform in the Internet. While there are exceptions, the vast majority of /22s and longer are in low-numbered ASes in North America, Europe, and AUSNZ. Due to a greater level of general civility, the prevalence of the rule of law, and the ability to have recourse against rogue operators, the incidence of rogue routing information from the locations above is orders of magnitude lower than that outside of it. Most North American Operators are, if not a full backbone themselves, directly connected to a true backbone provider, and therefore only 2 hops to any serious website. For North American operators, long prefixes advertised 3 or more BGP hops away are frequently forged. So, here are a few proposals: 1: Per my prior message, create a "SuperAS" that highly trusted entities (like MS, Google, Yahoo, etc) directly peer with, who everyone else peers with for routing information, from which ANY prefix-length will be accepted. 2: Have some sort of algorithm that inversely relates AS number to longest prefix accepted from. IE, you would accept a longer prefix with 701 as the originator (not the advertising peer) than 17557. 3: Filter prefixes longer than some constant * number of ASes in path, as opposed to some raw filter. Do not aggregate, simply do not import at all. I'd say that you should accept /24 only from 2 hops or less, /20 from 3, and maximum/default from beyond. These are simple ideas on how, without adding a whole lot of complexity, we might address some of the issues highlighted by today's "accident". Just trying to offer solutions that could be implemented easily. I'm sure many smarter than I can come up with better ones.

Power Fun at 151 Front Street, Toronto
by Joe Abley 23 Feb '08

23 Feb '08

Hi all, Today is Diesel Day at 151 Front Street, where the building owner shuts down all grid power to allow intrusive power maintenance to happen, and the building is fed by generator power only. At least one suite on the 6th floor has been affected by a generator failure, so far. Just thought I'd pass on the news, in case there's anybody here who is scratching their heads about equipment or sessions down in Toronto which seem to have no rational cause. Most ISPs in the building (and the TorIX) have engineers on-site; if you have equipment located there which needs some TLC and you have no immediate/regular access to remote hands, let me know off-list and I'll try to put you in touch with someone who has appropriate access: I'm not on-site, but I have phone numbers for people who are.

Update to the IPv4 Registry¹s Format and Content
by Leo Vegoda 21 Feb '08

21 Feb '08

This message has been sent to several lists. I apologise for duplicates. IANA has improved the format for the IPv4 Address Space registry. At the same time, the entries that were marked ³Various Registries² have been replaced with references to the Regional Internet Registry (RIR) that provides WHOIS and reverse DNS service for that /8 allocation. If you want to machine-process the IPv4 registry, the new fields are: * Prefix * Designation * Date * Whois * Status * Note where the Date will always be of the form ³YYYY-MM² and the status has the following possible values: RESERVED, LEGACY, ALLOCATED and UNALLOCATED /8 allocations that contain legacy assignments in them that are now managed by the RIRs have the text ³Administered by² in the Designation column. Legacy assignments refer to IP address allocations made before the RIR system was established. Reserved address space held by IANA does not have a date listed. The registry can be found at: http://www.iana.org/assignments/ipv4-address-space If you have questions about the structure of the new format, please send e-mail to iana(a)iana.org. Kind regards, Leo Vegoda Manager, Number Resources - IANA
