I find this study interesting because it's about data that people are sharing by default settings of their software and acceptance of EULA. Attending a RIPE/NANOG/IETF meeting is interesting seeing all the messages and disclosures from hosts that are broadcast. The same is true of CDP/LLDP and other protocols that operate within this space. If you haven't looked at the data your laptop leaks from running iTunes, mDNS/Bonjour, etc you may want to investigate it before joining an untrusted network. The apple messages app and itunes share a lot of data, plus even in just DHCP you see plenty of details. Example from my home: Client-Ethernet-Address c8:0a:a9:2d:c9:25 Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message Option 53, length 1: Discover MSZ Option 57, length 2: 576 Vendor-Class Option 60, length 21: "Broadcom:LB4M:1.1.0.8" Client-Ethernet-Address 5c:f9:38:da:d8:79 Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message Option 53, length 1: Request Parameter-Request Option 55, length 6: Subnet-Mask, Default-Gateway, Domain-Name-Server, Domain-Name Option 119, Option 252 MSZ Option 57, length 2: 1500 Client-ID Option 61, length 7: ether 5c:f9:38:da:d8:79 Requested-IP Option 50, length 4: 10.0.0.182 Lease-Time Option 51, length 4: 7776000 Hostname Option 12, length 15: "FamilyRAppleTV2" Take a look if you haven't studied this traffic. Keep in mind what this may do to the basic-1mbs rates supported on 802.11 radios and how a large broadcast domain with lots of fe80:: traffic for NDP will cause RF congestion due to speed changes. - Jared -- Jared Mauch | pgp key available via finger from jared@puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine.
