Re: CGNAT
by Jared Brown 04 Mar '21

Kevin, One of the presented options isn't like the others. As such the comparison isn't really fair, especially if you expect to run your business longer than 7 years. If you buy more IPv4 space you will neither have to deal with CGNAT nor worry about traffic growth. Both of those benefits are easily worth the (short term) premium. In the long term, buying more IPv4 blocks now is likely to be cheaper than running CGNAT for the foreseeable future. To echo Owen, in general, the economics today still work out to make purchasing addresses more favorable than CGNAT. - Jared Sent: Tue Feb 2314:36:48 UTC 2021 From: Kevin Burke kburke at burlingtontelecom.com To: nanog(a)nanog.org Subject: Re: CGNAT We are looking at implementing a similar solution with A10 for CGNAT. We've been in touch with A10. Just wondering if there are some alternative vendors that anyone would recommend. We'd probably be looking at a solution to support 5k to 15k customers and bandwidth up to around 30-40 gig as a starting point. A solution that is as transparent to user experience as possible is a priority. The numbers below are for a similar target of subscriber’s and peak bandwidth. We assumed a couple of numbers: Current Peak Bandwidth = 40G Remaining IPv4 traffic after migration = 20% (Seen references to 10% or 20% on this forum) Future Bandwidth Growth = 2x (no data behind this assumption) Future CGNAT’ed bandwidth = 15Gbps Equipment & budget lifecycle = 7Yr Getting that data led us to this price comparison: Solution Lifecycle/ Term Annual Cost/Sub Product Lifecycle Cost/Sub Lease IPv4 Cogent 7 $ 4.45 $ 31.13 A10 CGNAT 15Gb 7Yr 7 $ 1.21 $ 8.47 A10 CGNAT 40Gb 7Yr 7 $ 1.95 $ 13.68 Purchase @ $25 7Yr 7 $ 3.57 $ 25.00 The current plan is implement an A10 CGNAT solution after upgrading our network for IPv6. In the interim we will have to lease IPv4 to tide us over. I would be curious to see what other’s estimate the costs of various approaches. Feel free to ping me off-list for more specific numbers.

ROVv6 does not behave the same way as ROVv4: What rookie mistake(s) did I make?
by Pirawat WATANAPONGSE 04 Mar '21

04 Mar '21

Dear all, We just turned on our RPKI Route Origin Validation yesterday, then something weird happened: [Reference: We are running NLnet Labs’ Routinator 3000, feeding a Cisco ASR 1000 Series router. I know, I know, we haven’t started a second validator yet.] When we tested against the two testers: https://sg-pub.ripe.net/jasper/rpki-web-test/ and https://isbgpsafeyet.com/ the IPv4-only net-segment passed with flying color. [by the way, very sneaky you Cloudflare, registering the invalid block to the AS0 is a nice touch; I had to configure the router to really drop the invalid routes instead of just lowering their preference. Good show, mate!] However, when we tested on dual-stack net-segment, the first test passed, but Cloudflare invalids sneak through on the IPv6 side, causing the second test to fail. So, here comes the question: What rookie mistake(s) did I make? IPv4 and IPv6 configuration are supposed to be symmetry, right? Or did I miss something? And since I already start asking: For a “second validator”, which choice is better: second copy of the same software, or different software altogether? Thanks in advance for all comments and advices, -- Pirawat.

Trouble Playing Multiplayer Games from Reallocated IP Space
by Tim Nowaczyk 03 Mar '21

03 Mar '21

Hey NANOG, We have seen an issue where our customers who have IP addresses that are directly allocated to us can play online multiplayer games (NBA2k, NBA2k21, Fallout 76, and Stardew Valley were mentioned specifically) but when they have an IP that was reallocated to us by one of our Upstreams (Server Central), these games no longer work. I know NBA2k is behind Prolexic, but not sure about the others. 2k Games says that we, the ISP, must be blocking something, but there’s absolutely no difference in how data moves from our internet edge to the customer whether they have one of our IPs or one of the reallocated ones. We noticed that one geocoding provider has our reallocated IPs flagged as “hosting” IPs and maybe 2k is using some metadata like that to block our IPs. Does anyone have a contact at Prolexic who might be able to help? Thanks, Tim Nowaczyk -- Timothy Nowaczyk | Senior Network Manager office 703.554.6622 <tel:703.554.6622> | mobile 571.318.9434 <tel:571.318.9434>

IPv6 Multicast Routing&Registry
by Nicholas Warren 02 Mar '21

02 Mar '21

Does IANA (https://www.iana.org/assignments/ipv6-multicast-addresses/ipv6-multicast-ad…) run the registry for IPv6 Multicast groups? "We do not make allocations directly to ISPs or end users except in specific circumstances, such as allocations of multicast addresses" There are only 112 registered multicast addresses? That seems low. Are some IPv6 multicast packets globally routable? Wikipedia says both yes and no. Should we be allowing packets with multicast addresses in/out of our network?

London Interxion Data Centers
by Rod Beck 01 Mar '21

01 Mar '21

Hi Folks, My understanding is that there are three London Interxion data centers (I thought Equinix was the Borg and had assimilated pretty everything at this point). Trying to get the address where the facility where the London Metal Exchange houses its trading engine. No, financial institutions don't like to give this info to transport providers. The trading engine is the heart of electronic trading - it matches buy and sell offers. Regards, Roderick.
