Saw this excellent presentation in UKNOF 34 by Peter Stevens from Mythic Beasts. Really enjoyed the challenges and fixes he shared in running an IPv6 only web hosting. A must watch for geeks :) Also, UKNOF & NLNOG both seem to have excellent content in their conferences along with professional video recording which they make available over YouTube channels.
Enjoyed ISC’s presentation about their analysis of F root server (one 13 root DNS servers which power the Internet) about anycast performance gloablly for 22.214.171.124/24 announced (and anycasted) by AS3557 (ISC). This was presentation at UKNOF 32. Embedded presentation below (or click here to watch on YouTube directly)
