I have done VLSM calculations in my head ever since I learned them in college. Unfortunately, some of the CCIEs I know of, do not.
I suppose that is still better than the most to nearly all of the "network administrators" I met who have been "working in the field for years" that cannot understand any level of subnetting ("What's a slash /24, that's so complicated, I just call it the 255.255.255.0"), let alone even fathom binary numbers. > Just out of curiosity, how many CCIEs and people that have at least > had a shot at the lab can comfortably do VLSM calculations in their > heads? > > I think this is quite common among ISP operators, but I really don't > know about people in an enterprise orientation.
