I'm not sure whether this also applies to the others. From what I've gone through last few weeks:

- 218.111.* IP range is very slow most of the time, except for a few servers. Better choose other IP.

- When using certain modem & firmware, you may get dc at a specific time period. For example, I got Aztech DSL600EU with firmware version 38.53.1. It will dc around 12:00am-01:00am almost everyday. But when I switched to another Aztech DSL600EU with firmware version 62.53.2, there is no more dc and I can keep the connection for more than 24 hours.

- Not all 219.95.* IP range is bad. After a few try, I found out that the difference can be very noticeable. For example, 219.95.18.* IP is suck while 219.95.88.* can get full speed, even faster than 218.111.*

Anyway, can get fast connection as long as I know TMNut behavior lately.
