Hmm... I need to find out myself. I don't know what is the answer to that question. I'll do some research in Google and get back to you if I discover an answer. You should email the people at 123 reg as they probably could give you help..
But i'm writing article about this, so I can tell you more in few days..
Bit confused over the W being a vowel?.
5*21*6, CVCV starting with the letter Y.
20*5*5, CVCV with the letter Y in the middle.
I don't count a HostGator with consecutive Y's as a CVCV as it is not obvious if the Y is giving a vowel or consonant sound or both..
This brings the total to 15530.
If you include consecutive Y's then the total would be 21*6*21*6 = 15876..
Personally, I think that CVCV.com with Y as the second letter are very overated. I'd rather a VCCV.com or a very obvious one syllable CVCC.com or CCVC.com..
LLL.com are a lot better than CVCV.com. I can't see much $XXX,XXX demand for a CVCV.com in a rush. Low quality CVCV.com with a Q as the third letter are nowhere near as popular as LLL.com with bad letters...
The prices for cvcv are almost exclusively based on their "brandability" Perhaps every once in a while they will sell based on the actual letters, as an acronym, but in those rare cases, the fact that it is pronounceable is almost besides the point..
However, LLL's almost always sell based on acronyms. There are millions of companies, organizations and situations that have 3 words, far far less have 4, which makes the 3 letter have much more demand..
In addition, if you sell based on the specific letters of an LLL, then there will be a few end users that absolutely need to have this exact name. Whereas when you sell based on the brandability of a random pronounceable set of letters with no intrinsic meaning, they could just as easily have mino, nimo, bimo, limo, himo, etc....
As a result, an LLL will always have that huge end user potential, while the "brandable" cvcv names will not. Therefore, the only way that the price for cvcv will escalate to LLL prices is if they are consolidated in the hands of domainers who won't take less for any name. However, as long as I can get a different cvcv for 1k or so, I won't ever pay 10k or 20k for a different one, even a very good one...
I often think how one day all the LLL.com and LLLL.com domains are going to all belong to end users..
When that happens, we'll all be talking about our rare LLLLLLLL.com's then!..
To me, most of the time a CVCV is easier to remember than a random LLL...
