• Gulliver Project
![Page 3: DNS Measurement Activity on ITB 2010](https://reader033.fdocuments.net/reader033/viewer/2022060107/554bae7ab4c905ae618b56b5/html5/thumbnails/3.jpg)
Overview
• ITB is participating in Internet measurement
activity, especially DNS
• Participation in global Internet community
for international exposure

DNS @ ITB
• 3 Production Servers
– ISC BIND 9.6.2
– DNSSEC not enabled
– Anycast distribution
• 1 Experimental Server
– NLnet Unbound 1.4.4
– DNSSEC (validation) enabled
– ISC DLV (DNSSEC Lookaside Validation)

Monitoring on ITB side
• Using Munin plugins for Bind & Unbound

DITL 2010
![Page 8: DNS Measurement Activity on ITB 2010](https://reader033.fdocuments.net/reader033/viewer/2022060107/554bae7ab4c905ae618b56b5/html5/thumbnails/8.jpg)
DITL 2010
• A Day In The Life of the Internet
– https://www.dns-oarc.net
• ITB is participating in DITL 2010 in April
• Conducted by Dian Dwi Nugraha (DNS
Admin)
![Page 9: DNS Measurement Activity on ITB 2010](https://reader033.fdocuments.net/reader033/viewer/2022060107/554bae7ab4c905ae618b56b5/html5/thumbnails/9.jpg)
What it is?
• A large-scale data collection project undertaken
by CAIDA and OARC (Operations, Analysis, and
Research Center) every year since 2006
• Participants :
– DNS Root Servers
– TLD Servers
– AS112 nodes
– “client-side” iterative/caching resolvers
• Tool : dnscap/tcpdump

Objectives
• Measure Internet growth
– IPv4 and IPv6 growth
– Secure/insecure DNS growth
• Uncover possible DNS anomalies in process
![Page 11: DNS Measurement Activity on ITB 2010](https://reader033.fdocuments.net/reader033/viewer/2022060107/554bae7ab4c905ae618b56b5/html5/thumbnails/11.jpg)
Data taken
• IPv4/IPv6 source and destination query
• qps (queries per second)
• secure/insecure (DNSSEC)
• RRsets (A,AAAA,MX,NS,...)

GULLIVER PROJECT
![Page 16: DNS Measurement Activity on ITB 2010](https://reader033.fdocuments.net/reader033/viewer/2022060107/554bae7ab4c905ae618b56b5/html5/thumbnails/16.jpg)
What is it?
• Active Measurement Framework
• Probes DNS reachability from worldwide locations
– RTT, Query Timeout
– Node ID (hostname.bind or server.id)
• 30 Probe Locations as of Feb. 2010
– Including South/East Asia and Africa countries
• Targets
– Root, ccTLD, in‐addr.arpa DNS servers
• http://gulliver.wide.ad.jp/
