Does that matter?

ok so I just mirgrate my site to a new host

funny is I go Adsense dashboard ,

saw this

the first site for an example is abc. com which all along just one url

than after I migrate , show www. abc .com

yes I only got one site , but why Adsense show another url of mine is www. ?


does that matter?

My site does so far ok , adsense ad display as usual
