The largest "named numbers" are mathematical concepts (e.g. Graham's Number), followed by the googleplex 10googol and googol 10100.
The largest number that continues the -illionnomenclature is the centillion (10303 "short scale").
A number that is among the largest regularly used is the decillion (1033 "short scale")
The number 1 less than a decillion
(1,000,000,000,000,000,000,000,000,000,000,000,000)
is 999,999,999,999,999,999,999,999,999,999,999
or in words:
Nine hundred and ninety-nine nonillion,
Nine hundred and ninety-nine octillion,

Infinity
Infinity is not a number; it is a concept. There is no highest number, because you can always add 1 to it and create a higher number. If this new number is the highest number, then add 1 again and it isn't. The process can never end, so infinity is used to describe the idea: a process that never ends.
There is no "Highest" number, as they go on into infinity.
