De-bogonising 2a10::/12
by Nikolas Pediaditis 13 Jan '20

13 Jan '20

Dear colleagues, A few months ago the RIPE NCC became the first RIR to receive an additional /12 IPv6 allocation (2a10::/12) from IANA. We will soon begin to delegate space from this IPv6 block to LIRs. Prior to this, in order to improve routability and minimise the risk of filtering, the RIPE NCC will perform several de-bogonising activities in the next few weeks. We plan to start announcing the full /12, as well as a few /32 or longer blocks out of 2a10::/12 from AS12654 (RIPE Routing Information System (RIS)), within the next few days. We will analyse data from RIS and RIPE Atlas and we plan to write up an analysis around this effort. We want to remind everybody to update their bogon filters and allow routes originating from 2a10::/12 in their network. Kind regards, Nikolas Pediaditis Registration Services and Policy Development Manager RIPE NCC

Starting to Drop Invalids for Customers
by Mark Tinka 11 Jan '20

11 Jan '20

Hi all. Just to let this group know that we've started the process of activating the dropping of Invalids for all our eBGP customers. We're starting off with our Juniper edge routers. Once those are done, we'll move on to our Cisco ASR1006 routers, finishing off with our Cisco ASR920 routers. I'll let you know if anything catches fire :-). Mark.

Sharp drop in IPv6 traffic on AMS-IX on January 10th, 2019

11 Jan '20

Hi all, /u/tambry on Reddit [0] posted about there being a sharp decline in IPv6 traffic on AMS-IX today. A ~60G drop from peak looking at the graphs here: https://stats.ams-ix.net/sflow/ipv6.html Anyone know what happened or any ideas as to what the cause in such a sharp drop might be?

Cost Recovery Surcharge & Va Personal Property Tax Recovery for IP Transit
by Siyuan Miao 10 Jan '20

10 Jan '20

NANOG, We've recently signed contract of colocation + IP transit with a local provider in Northern Virginia. Co-location services is okay but we found something unusual on our IP transit invoices. - Va Personal Property Tax Recovery (1.8%) - Cost Recovery Surcharge (3%)? We've talked with our providers but they told us: > we use a tax engine that provides the taxes/rates to our services. If you would like further language on them, please let me know and I will have some one send that over. Has anyone else ran into this? If this is a legit "surcharge"? Also, IP transit isn't a property, why is there a "Property Tax" for IP transit? Regards, Siyuan Miao

help with diagnosing traffic blackhole to / from select akamai ranges?
by William McLendon 09 Jan '20

09 Jan '20

Good afternoon, we have a downstream customer originating a more specific /24 prefix, and when they do so, traffic sourced from that /24 prefix to at least a subset of akamai ranges (at minimum the 184.27.24.0/22 block at this time) are getting blackholed somewhere along the path either to or from, but i’m not sure how best to go about troubleshooting or getting assistance with diagnosing where the problem may be. from a device in the offending IP block I cannot ping or curl to www.akamai.com <http://www.akamai.com/> that resolves to 184.27.25.72, however from an IP outside the /24 specific prefix but still in their supernet range I am able to ping and get an HTTP 301 redirect response. Some other akamai prefixes like 23.73.0.0/20 seem to work without issue from what I can tell thus far. If the /24 prefix is removed, all works as expected via their covering announcement (which does return via their primary provider, as we are generally a backup path for their larger block). Any guidance the community can share as to how to go about trying to resolve I would greatly appreciate — this is the first time i’ve had to trace down a [seemingly random] reachability issue like this. Connectivity to other services seem ok from what I can gather so far, even to some other akamai ranges. from looking glass perspective it looks like the route is being accepted properly by our upstreams and other large providers like NTT, etc. I did send an email to noc(a)akamai.com <mailto:noc@akamai.com> but not sure that is the appropriate way to reach out for assistance or not, since we nor our downstream customer are direct customers or peers of theirs. Thanks, Will McLendon wimclend(a)gmail.com <mailto:wimclend@gmail.com>
