Your DNS Servers are not working correctly.
by Mark Andrews 12 Apr '23

12 Apr '23

I work for a DNS vendor and saw reports about DNS resolution errors when looking up names under dhhs.gov. It looks like your servers are not returning non-existence answers over UDP which breaks servers that are trying to do DNS QNAME minimisation (See RFC 7816). Below are three queries that the servers should be capable of answering if they are following the DNS protocol correctly. dhhs.gov is answered but foobar.dhhs.gov doesn’t return anything and I would expect a NXDOMAIN (Name Error) response. Additionally 355.dhhs.gov should be returning a NODATA/NOERROR response at a minimum as it part of your DNS servers names. If I ask the same questions over TCP instead of UDP I get answers. This really smells like a misconfigured firewall.

by Jeffrey Haas 11 Apr '23

11 Apr '23

The IETF BGP YANG module authors would like to draw your collective attention to a Working Group Last Call that has begun for the IETF BGP YANG module. This module provides the base for core IETF BGP technologies, and will serve as the primary point of extension for BGP-related technologies modeled in YANG in the IETF, including the BGP portion of VPN technologies. Your operational wisdom and scrutiny would be greatly appreciated. A URL for the WGLC mail is here: https://mailarchive.ietf.org/arch/msg/idr/263_yrn_ZnNRokmUwgye7Id5mHo/ For those of you who haven't participated in IETF mail lists before, the IDR datatracker page has subscription information for the mailing list: https://datatracker.ietf.org/wg/idr/about/ Thanks! -- Jeff (for the authors) > Begin forwarded message: > > From: "Dongjie (Jimmy)" <jie.dong(a)huawei.com> > Subject: WG Last Call on draft-ietf-idr-bgp-model-16 > Date: April 10, 2023 at 10:17:26 PM EDT > To: "idr(a)ietf.org" <idr(a)ietf.org> > Cc: "idr-chairs(a)ietf.org" <idr-chairs(a)ietf.org>, "Dongjie (Jimmy)" <jie.dong(a)huawei.com> > Resent-From: <alias-bounces(a)ietf.org> > Resent-To: skh(a)ndzh.com, keyur(a)arrcus.com, jhaas(a)pfrc.org, jie.dong(a)huawei.com > > Hi WG, > > This begins the Working Group Last Call for "YANG Model for Border Gateway Protocol (BGP-4)", draft-ietf-idr-bgp-model-16.

Please reply to the list with your comments. Considering this is a long document with a big YANG model, the last call will last for 4 weeks and conclude on Sunday, 7 May, 2023. > > The authors are requested to state whether they are aware of applicable IPR related to this draft. Similarly, if others in the Working Group are aware of applicable IPR, please also disclose them. > > People are encouraged to indicate whether there is implementation of this document.

Auth0 geolocation?
