AAAA's for www.netflix.com
by Frank Bulk 08 Jun '12

08 Jun '12

I started monitoring IPv6 access to www.netflix.com after seeing this posting (http://www.personal.psu.edu/dvm105/blogs/ipv6/2012/06/netflix-is-back.html) and what I found, over the week, was that access was coming and going (www.premieronline.net/~fbulk/netflix.png) But not because of IPv6 connectivity, but because the AAAA's were coming and going. Netflix's DNS TTL is pretty short. I assume Netflix has some global DNS load balancing so my perspective may not be complete. Has anyone else been seeing this? I contacted a Netflix employee (he's well known on this list) and he responded once but I haven't heard back since Saturday. Here's some sample queries from Saturday and today. ========================================================= nagios:/home/fbulk# dig AAAA www.netflix.com ; <<>> DiG 9.7.3 <<>> AAAA www.netflix.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 26825 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;www.netflix.com.

Configuration Systems
by Andrew Latham 07 Jun '12

07 Jun '12

Lurker speaking... beware... I have been talking with some folks from various industries about configuration systems ala Bcfg2, Puppet, Chef, and others. Many of them care far too much about the current nodes configuration status as some admin had logged in and changed something. I am authoring a system called Enablement that uses what ever technology needed (ssh, telnet over admin vlan, rsh, etc...) to push a planned system/config to the device. Monitoring and auditing are all the same at the moment as we need historical data on when a service or port started and stopped offering its planned or unplanned service. For a meeting Thursday I am looking forward to the future of configuring systems. My idea is push + netblock scanning of services. With stacks for clouds we can startup and shut down nodes easy. Would a bend over backwards config reader for all the "Configuration Management Systems" be the best medium ground from the service provider point of view? Enablement.... Send another man to fight on the front line. -- ~ Andrew "lathama" Latham lathama(a)gmail.com http://lathama.net ~

.GW registrar?
by Ben Carleton 06 Jun '12

06 Jun '12

Hello all, Does anyone have a contact at either DENIC or "Fundação IT & MEDIA Universidade de Bissao" that can advise if registrations are currently being accepted for .GW domain names? The IANA admin contact, admin(a)register.gw, is at a domain with no valid MX records (or A records, for that matter). The technical contact is listed as DENIC. TIA, -- Ben Carleton
