find the missing number, or explain the sequence

Time for a clue,

17576

 

[aZooZa]

Not really too 'mathsy' so:

26^3 = 17576 = number of 3 chars/numbers domains allowable in ASCII

48 to 57 (numeric 0-9)

65 to 90 (alpha A-Z)

Not the answer though, but is it a step in the right direction?

The first numbers are ports

232 TCP
587 Email
43 WHOIS
118 SQL

 

[keys]

it's all about letters, represented numerically

 

[WigWam]

I'll start with the clue: 17576
= alphabet split into 5 rows
A
BCDEFGH
IJKLM
NOPQRST
UVWXYZ

17576 = 26 is a fascinating coincidence, but not employed in this teaser
