Well Alex,

Here are the first 100 Fasthosts mass-registered .uk names, working numerically and alphabetically (forgive me for not disclosing the other 100,000s they also mass-registered, but we each do our own homework):

*It's feasible that 1 or 2 of these have now been claimed by the original .co.uk holders, but frankly the vast majority will drop because the registrants never wanted the .uk names, never asked for them, never agreed to being named as the 'registrants' (or you might say 'ghost registrants').
In total, Fasthosts mass-registered 797 domains starting with a number, and that's before you even get to names that start with the letter 'A'...
There are "alot" (.uk)...
