I was attempting to determine how many different combinations of strings can be created from 37 characters, where the string can be up to, but no longer than 63 characters.
I'm not a math person and was hoping to find a calculator online to get me to the total number of combinations. The trick seems to be the "up to" limit of the length. A one character string counts, a nine character counts, etc., just as a 63-character string would count. I'm thinking this would be some huge number.
P.S. Practically-speaking, I'm curious how many different subdomains I can use with the available character set (commas and "and" excluded): 0,1,2,3,4,5,6,7,8,9,-,q,w,e,r,t,y,u,i,o,p,a,s,d,f,g,h,j,k,l,z,x,c,v,b,n, and m
So a hostname could be any combination of those 37 characters with variable string length up to 63 characters, then the domain name, then the top-level domain. [1...63 characters of the 37].domain.top-LevelDomain .
