Contact details for an Irish visa application (Long stay D)

Hi, I hope someone could help me with my query.
I’ve started my online application for a long stay visa to Ireland as a spouse of an Irish citizen. As I’m filling my application in there’s a question about contact details for contact /host in Ireland. The thing is my family and I are only going to relocate to Ireland from the UK and we haven’t got a place yet as we’d like to apply for a visa first and then my husband will travel to Ireland to find accommodation.
Has anyone got any experience in this matter and what are the requirements for this particular section in the application?

I would really appreciate your help.
Thanks.
