The number of 6to4 relay routers has been the subject of debate, as additional routers increase the scalability and efficency of the 6to4 system. Counting public relay routers is easy using the global routing table. This paper outlines a technique that can count private relay routers and reports results of applying this method. Our results indicate that there are a significant number of private relays in operation in comparison to the number of public relays. This number has increased over the last two years. The results also indicate that using distributed traceroute facilities to measure the multiplicity of an anycast deployment requires large numbers of nodes to be accurate\n          <\/jats:p>","DOI":"10.1145\/1111322.1111340","type":"journal-article","created":{"date-parts":[[2006,2,6]],"date-time":"2006-02-06T18:14:10Z","timestamp":1139249650000},"page":"79-82","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Counting 6to4 relay routers"],"prefix":"10.1145","volume":"36","author":[{"given":"David","family":"Malone","sequence":"first","affiliation":[{"name":"Hamilton Institute, NUI Maynooth, Ireland"}]}],"member":"320","published-online":{"date-parts":[[2006,1,10]]},"reference":[{"key":"e_1_2_1_1_1","unstructured":"Nlanr's active measurement project (AMP). http:\/\/watt.nlanr.net\/.
