This is what I get:
Unfortunately we have been unable to identify your ISP from your ISP address. This could either be due to:... etc
So effectively it's not recognising Tiscali.
It should recognise most of Tiscali's - eg when Tiscali declare themselves as say DSL-TISCALI-UK or VIDEONETWORKS...
Its just unfortunate that the particular IP that theyve allocated you is showing as belonging to UK-TELINCO and they put down their organisation as TUL3-RIPE . Even the RDNS is showing as dynamic.dsl.as9105.com. Its a bit hard to resolve something if the ISP doesnt declare who they are :/
I've manually added the block of IPs so it should now work.
The more people I get advising me that a particular block doesnt work - then I can soon add it and the system will work in future for others.
So if anyone does get any more like this please do let me know as it helps build up the database.
If it cant resolve an IP range it should automatically bring up a "we have been unable to identify your ISP from your ISP address" message with a direct contact link to advise me of the problem.
Thanks Floydy - you telling me helps me build up the list for future
