Siro/OpenEir FTTH ISPs - Connection Type

I'm hoping to get either connected for Siro or OpenEir in our estate soon. TLI have finished their work for the Siro installation from talking to them. KN have been around doing the work for OpenEir and the next step for them is for it to be spliced.

According to the Siro website, I should have a choice of the following ISPs, the OpenEir network would probably be the same.

• Airwire
• Digiweb
• Sky
• Vodafone
• Pure Telecom

I'm leaning towards going with Digiweb or Airwire. My question is do any of the above ISPs put you on IPv6 or ds-lite (like Virgin used to or still do?)

The reason I ask is that I'll need to be put on IPv4 when I do get connected to properly work from home.

I've seen posts here from people who are on IPv6 with Airwire here before, but not for the others.
