I promise I will not be a knowledge leech, I will contribute what I know as
well.   Ofcourse I do have a question regarding IP Summaization:   Up untill
today I thought I had summarization down cold until I tried a few self made
excercises.   The formula I used to gather a summ address was 2n=x.  Thats 2
to the n power equals x.
x is the number of subnets that you want to summarize and n will be how much
you subtract from the lowest mask of those subnets.  for example:


216.52.146.136/30
216.52.146.140/30       
216.52.146.144/30       
216.52.146.148/30

using that formula the summ would be 216.52.146.136/28  which is not a valid
route. Hoever that formula works here:
216.52.146.48/29        
216.52.146.56/29        

summ route:     216.52.146.48 /28

I guess my question is, what is the best/effective/convient way to derive
summary addresses?  Thanks for any input.
