IP summarization for exact match of IP addresses.

[Deepak Ambotkar]

Hello,

I came across a range 25 of IP addresses with /32 mask and they are back to back. I am wondering if I can summarize them but since this is a DC firewall I do not want to summarize to the typical range of IP addresses. I want to summarize those addresses where exact IP addresses will be matched.

Below is the range I am summarizing:-

10.82.194.211-10.82.194.236

According to standard summarization it is 10.82.194.192/26 but I do not want the entire block starting from .192. The summarization should include only the IP's from .211 to .236

I am not sure if we can do this with Boolean algebra.

Thanks in advance,

Deepak A.

Hello,

it would possibly work with those summarizations:

10.82.194.211/32

10.82.194.212/31

10.82.194.216/30

10.82.194.224/30

10.82.194.232/31

10.82.194.236/32

I think there is no easier way to summarize this particular range.

Please correct me if I miscalculate.

Hello Tobias,

You are right, but you have mistakenly shift one bit in subnet mask.

10.82.194.211/32

10.82.194.212/30

10.82.194.216/29

10.82.194.224/29

10.82.194.232/30

10.82.194.236/32
