JPRS observed that DS queries for JP registered domain names have been increasing and 3.5% of queries are qtype DS now.
I make a presentation about it at DNS-OARC 2013 Spring workshop and I wrote a draft as a DNSSEC side effect. Presentation material is here: https://indico.dns-oarc.net/indico/getFile.py/access?contribId=14&resId=0&materialId=slides&confId=0 Do you observe an increase of DS queries ? Comments appreciated. A new version of I-D, draft-fujiwara-dnsop-ds-query-increase-00.txt has been successfully submitted by Kazunori Fujiwara and posted to the IETF repository. Filename: draft-fujiwara-dnsop-ds-query-increase Revision: 00 Title: Side effect of DNSSEC: an increase of DS queries Creation date: 2013-06-07 Group: Individual Submission Number of pages: 5 URL: http://www.ietf.org/internet-drafts/draft-fujiwara-dnsop-ds-query-increase-00.txt Status: http://datatracker.ietf.org/doc/draft-fujiwara-dnsop-ds-query-increase Htmlized: http://tools.ietf.org/html/draft-fujiwara-dnsop-ds-query-increase-00 Abstract: A significant increase of periodic DS queries is observed at top level domain (TLD) DNS servers. Currently, almost all of periodic DS queries come from DNSSEC validators and are queries for unsigned delegations. The reason of the increase is low NCACHE TTL value and DS nonexistence. This phenomena is DNSSEC protocol and DNS parameter issue. DS queries will increase as DNSSEC validators will increase. -- Kazunori Fujiwara, JPRS <[email protected]> _______________________________________________ DNSOP mailing list [email protected] https://www.ietf.org/mailman/listinfo/dnsop
