Technicalities of cable high-speed internet access

[Conan Kelly]

Hello all,

I've heard that cable high-speed internet access is shared. If I went this
route, I could be sharing my connection with my neighbors, thus slowing my
connection. I've also heard that providers WILL NOT tell you how many
households are on you segment.

In the 85022 zip code of Phoenix, AZ, Cox Communications offers 4
levels/tiers of high speed internet access. My question is, would I share
my connection with my all my neighbors whom subscribe to any level/tier of
service, or would I share it with just the ones whom subscribe to the same
level/tier of service that I subscribe to?

Also, since cable companies will not disclose how many households are on my
segment, how many households could be on my segment? 100? More? Less?

Thanks for any help anyone can provide,

Conan
