How Many Wirral Domains Are There?

I was wondering how many domains are indexed that are explicity Wirral related. I say indexed because of course there could many domain names that are:

• inactive
• parked (parked domains are not always indexed)
• not yet spidered by the search engines
• blocking the search engines via robots.txt

Of course, there could many sites (mine for example, or our famous golf club) that are Wirral related but have an unrelated domain name. Anyways, using the allinurl:wirral*.co.uk construct I can see that approx 81,000 domains that include Wirral in the URL before the .co.uk are currently indexed. Try it yourself using this search and see what results you get.
