My ISP allows high interconnect speeds. How do I take advantage.

I am on a BW limited connection with max ul/dl speed of 150kbps. However everytime I connect to a peer using the same isp ( ip = isp.isp.x.x), the ul/dl speeds zoom upto 10MBps.

Is there anyway I can prioritize this sort of connections? I would like to have a first preference for connecting to peers from same isp.

In general, you can't. Mostly due to the distributed nature of bittorrent, when you connect to the tracker it only gives you a subset of peers. When this is say 80 of "1000" peers connected it's a low likelihood that those will be on your ISP. Bittorrent, Inc. did some benefit to this by proposing BEP 22 http://bittorrent.org/beps/bep_0022.html which allowed transparent cache servers on the ISP level to keep data accessible on-network as opposed to going off-network. This is basically the reason your speeds shoot up on the same ISP

However since it's a new proposal and most other proposals rely on the ISP (which IPs do you own, are on your network-segment, in-network).. you can only guess for things like ipfilter.dat

Long answer; for new/popular content you could theoretically enable ipfilter.dat and put in all IP addresses not on your network (bandwidth outbound incurred) in there. However you would need to rely on others and your ISP for data in that regard.

Different answer. If your ISPs network is in-fact a private NAT (192.168.x.x 172.16-31.x.x or 10.x.x.x) you could use uTorrent's innate "local peer discovery", but it would require you to not have any router between you and your ISP which means you SHOULD definitely have a software firewall enabled 24/7 (Windows Firewall integrates with uT).

You could also run 2 copies of uTorrent, with one set up to block all but local ips. The local ip one could be set to much higher speeds.

Future versions of uTorrent hopefully will have settings for 2 tiered internet or separate user-customizable internet/LAN settings.
