There are TR members who specifically seek out problems in need of a solution. Although there is some overlap between the forums, you'll find more of those members in 'Q&A' than in 'Discussions' or 'Water Cooler'.
Be sure to use the voting buttons to provide your feedback. Voting a '+' does not necessarily mean that a given response contained the complete solution to your problem, but that it served to guide you toward it. This is intended to serve as an aid to those who may in the future have a problem similar to yours. If they have a ready source of reference available, perhaps won't need to repeat questions previously asked and answered. If a post did contain the solution to your problem, you can also close the question by marking the helpful post as "The Answer". . .

Result: 192.168.10.64/28 >> 255.255.255.228
It is a 30 Bit Mask, so you have to focus on the fourth octet, but it is better you just concenrate on 32 bits instead of octets. Convert the decimal to binary format and take the common bits out of the 30 bits.
Here the first 28 bits are common, so the mask is 28, which is 255.255.255.240(255-15)
