________________________________________________________________________ AS0 RPKI system deployed in production (Prop132) ________________________________________________________________________ The AS0 RPKI system previously in test has now been deployed to production. This completes implementation of APNIC Policy Prop132 "RPKI ROAs for unallocated and unassigned APNIC address space" https://www.apnic.net/community/policy/proposals/prop-132 A new TAL is being used which can be fetched from: https://tal.apnic.net/apnic-as0.tal Alternate forms of this TAL are also available and are documented at: https://www.apnic.net/community/security/resource-certification/tal-archive/ Please replace any prior TAL configuration in your RPKI validation systems. If you are not using this TAL consider adding it to get notification of authenticated denial of unallocated resources in the APNIC region. A report on deployment will be presented at APNIC50. This service will be discussed in the APNIC Routing SIG at the meeting, and subsequently on the mailing list: https://www.apnic.net/community/participate/sigs/routing-sig/ A blog article describing the deployment methodology is available at: https://blog.apnic.net/2020/09/02/policy-prop-132-as0-for-unallocated-space… Caveats and warnings about the use of this AS0 ROA are documented at: https://www.apnic.net/community/security/resource-certification/apnic-limit… ________________________________________________________________________ APNIC Secretariat secretariat(a)apnic.net<mailto:secretariat@apnic.net> Asia Pacific Network Information Centre (APNIC) Tel: +61 7 3858 3100 PO Box 3646 South Brisbane, QLD 4101 Australia Fax: +61 7 3858 3199 6 Cordelia Street, South Brisbane, QLD http://www.apnic.net ________________________________________________________________________

I have checked all of our circuits in the LA area and are seeing no BGP issues, but we don’t provide transit for CL, only use them for DIA. Traffic flows appear normal, but early Sunday morning is normally the lowest time of the week. -mel beckman > On Aug 30, 2020, at 5:29 AM, Mel Beckman <mel(a)beckman.org> wrote: >

Re: TCP and UDP Port 0 - Should an ISP or ITP Block it?
by K. Scott Helms 26 Aug '20

26 Aug '20

To be clear, UDP port 0 is not and probably shouldn't be blocked because some network gear and reporting tools may mistake a fragmented UDP PDU for port 0. That's an implementation error, but one that may be common enough to create issues for users. Blocking inbound TCP port 0 is something that I've personally done in dozens of ISP networks over more than a decade without a single reported issue.
