The number of complaints I've heard that "DNS resolvers eat *so* much memory" suggests that few people tweak the default configuration. 8-( However, it's unlikely that this was the cause of Comcast's problems because DNS cache overflows would have an impact on a much larger scale. -- "Fergie", a.k.a.
