Can you please check my math for errors? Based on the English Language and number Sets I decided to sit down and figure this out. 1 Digit Domains (N) There are 10 digits 0-9 1 Letter Domains (L) There are 26 characters available 2 Digit Domains (NN) there are 100 combinations of two digits from 0-9 2 Digit Hypen Domains N-N there are 100 combinations of two digits from 0-9 using hyphen in the middle 2 Letter Number Hyphen Domains (L-N N-L) There are 520 possible combinations of Letters A-Z and numbers 0-9 3 Digit Domains (NNN) 0-9 has 1000 combinations for 3 digits 4 Digit Domains (NNNN) 0-9 has 10000 combinations for 4 digits 2 Letter Domains (LL) A-Z has 676 combinations of two digits from A-Z 3 Letter Domains (LLL) A-Z has 17,576 combinations of 3 letters from A-Z 3 Letter Combination Domains (NNL NLN NLL LLN LNL LLN) There are 46,656 total combinations of 3 number letter characters Domains using 0-9 and A-Z Considering these as premium domain names there is a total of 76,044 character combinations. Excluding NNNN there are 66,044 total combinations. If We now consider the main TLD extensions in use in the usa .COM .NET .ORG .BIZ .US .INFO .MOBI .NAME We have a total possible domain registrations of 3 character domains at 528,352
I'm getting 28,080 for the six combos above. NNL=10*10*26=2600 NLN=10*26*10=2600 NLL=10*26*26=6760 LLN=26*26*10=6760 LNL=26*10*26=6760 LNN=26*10*10=2600
I can't be bothered to sit down & work this out, lol. But how did you come to the conclusion that .NAME is one of the main extentions? It is probably one of the crappiest & useless extentions out there.
DRT did this for me lol, i sat down and did this a while ago too, and there was like 30,000 LLLL.com names left (available) or something like that
Too many people base the value of a premium domain on the 3 character domain name price list. I value the N-L N-N L-N domains much higher since they are rare. Above the generic LLL and below the NNN I am a minority because they are hard to market. But like anything else its supply and demand. But given the choice I would much rather have cow.com than a-2.com Last check I think there were only approx 4000 3 character words in the english language do date.
