I do understand network masking but I don't understand what 126/8 is. I
had assumed that this would mean 126.x.x.x/8 but that wouldn't fit with
MCSE, MCP+I, CCNA
CNA 5.x, A+

Is a good start.
Very quick- the "slash number" (/8, /16, /24 etc) defines the number of
bits in a subnet mask. This is known as CIDR notation (Classless
Internet Domain Routing). This superceeds the older, classful
(A/B/C/D/E) networking. See also RFC 1519.
