/24 prefix "hijackability" metric (defining "better than avg AS")
by nusenu 25 Sep '18

25 Sep '18

Hi, I'm currently estimating how "vulnerable" certain IP addresses are to BGP hijacking. To do that, I put them into different categories (multiple can apply): a) RPKI validity state is "NotFound" (no ROA) and IP located in a prefix shorter than /24 (IPv4) or /48 (IPv6) b) Valid ROA but weak maxlength c) Valid ROA with proper maxlength d) is announced in a /24 prefix (IPv4) or /48 (IPv6) e) = (c) + (d) In addition to the distinction of prefix length (/24 vs. </24) I'd like to subcategorize /24 prefixes into - /24 prefix located in "well" connected AS (attacker's BGP visibility is presumed lower than the authentic AS visibility) - /24 prefix located in "poorly" connected AS (better for the attacker) The question is: What is the threshold and metric to tell these two apart? I'm having 3 approaches in mind and wanted to hear if you have any preferences, opinions or other approaches: Approach 1: ----------- If avg AS PATH length as provided by [1] is <2 in more than 50% of given locations and DE-CIX and AMS-IX is among them, then consider it a "well connected AS" Approach 2: ----------- Use CAIDA's AS rank data and define the top 50% ASes as "well" connected Approach 3: ----------- define "well connected" as avg AS PATH as seen in [1] is shorter than the global avg. AS PATH length (defined in [2]) Also: If there are already well established metrics for "well connected" AS I'd be happy to hear about them. Currently I'm leaning towards approach 1 as it is probably the strictest and most conservative approach. I also might compare the results of all 3 approaches. thanks! nusenu [1] https://stat.ripe.net/docs/data_api#AsPathLength [2] http://thyme.rand.apnic.net/current/data-summary (the mean value would actually be more interesting than the avg) Because it is hard to collect ROV data and the list on https://rov.rpki.net is still short I do not try to include a ROV metric (yet).

New on RIPE Labs: Upstream Visibility - Monitor the Visibility of your Prefix
by Mirjam Kuehne 25 Sep '18

25 Sep '18

Dear colleagues, Upstream Visibility is the new tool produced by the Computer Network Research Group of Roma Tre in collaboration with the RIPE NCC. It is a web application which proposes a concise way of visualising interdomain routing data of a specified prefix. Please find more details on RIPE Labs: https://labs.ripe.net/Members/massimo_candela/upstream-visibility-monitor-t… Kind regards, Mirjam Kühne RIPE NCC

Multi home BGP reestablishment.

I received a complaint from one of our important client is having issues for their BGP peer connectivity with their one upstream ANSs (AS 3xxx I. e Level 3 ) network. My research and development was as following details: • Run BGP protocol • configure BGP peering sessions against one of unestablished edge,(i. e Level 3 ) using peer groups • and then advertise networks. [N. B I used some dummy character here in this example to hide real network IPs ANSs info.] Info: The max number of VTY users is 10, and the number of current VTY users on line is 1.

Towards cleaning up RPKI INVALIDs
by nusenu 17 Sep '18

17 Sep '18

Hi, we made an analysis of the RPKI INVALIDs and broke them down by * RIR * INVALID reason * causing ROA * number of members each RIR would have to contact to fix them after filtering them to those prefixes that actually would become unreachable in an ROV environment. https://medium.com/@nusenu/towards-cleaning-up-rpki-invalids-d69b03ab8a8c Looking forward to comments from the WG and RIPE NCC. The central question in the direction of RIPE NCC is: Would you be open to reach out to your affected members to inform them about their affected IP prefixes? (as has been suggested by Job Snijders before) kind regards, nusenu -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu

RIPE NCC RPKI Validator 3 API spec?
by nusenu 14 Sep '18

14 Sep '18

Hi, (I hope it is ok to ask validator questions on this WG ML, but feel free to point me to a more appropriate venue) I'm using RIPE NCC's RPKI validator 3 and was looking for some API specifications that would describe the functioning of every parameter. Currently I'm making certain assumptions which is ok for some proof-of-concept but would like to confirm them using some official documentation. Is there a detailed specification that goes beyond [2]? thanks, nusenu [1] https://github.com/RIPE-NCC/rpki-validator-3/wiki [2] https://rpki-validator.ripe.net/swagger-ui.html#!/bgp45preview45controller/… https://www.ripe.net/support/documentation/developer-documentation/rpki-val… -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu

A measurement of the RPKI adoption of the >3k Tor prefixes
by nusenu 25 Aug '18

25 Aug '18

Hi, since I used your data, API (RIPEstat) and tools (RPKI validator) I figured I send you also my IRR and RPKI measurement results: https://medium.com/@nusenu/how-vulnerable-is-the-tor-network-to-bgp-hijacki… Thanks for making RIPEstat available for everyone. If anyone can comment on how hard it is to get a ROA for a legacy IP block for a RIPE member without converting it to ALLOCATED PA block first, that would be interesting. Also: is there any reason why a RIPE member would prefer to retain the LEGACY status? (instead of converting it) thanks, nusenu btw: While collecting the IRR data I stumbled on a problem with RIPEstat where it would say there is no IRR entry but NTTCOM actually had it (Christian is looking into it). https://stat.ripe.net/data/prefix-routing-consistency/data.json?resource=36… (if you change it to /17 the expected record will appear) "routes": [ { "origin": 10013, "irr_sources": [], <<<<------------------- "in_whois": false, <<<<------------------- "asn_name": "FBDC - FreeBit Co.,Ltd.", "prefix": "36.55.0.0/16", <<<<------------------- "in_bgp": true } vs whois -h rr.ntt.net 36.55.0.0/16 route: 36.55.0.0/16 descr: FreeBit CIDR origin: AS10013 notify: noc(a)FreeBit.NET mnt-by: MAINT-FBDC changed: y.ishizaki(a)FreeBit.NET 20120821 source: NTTCOM -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu
