Just ignore it. The ISP generally doesn’t care, and the claimant still has nothing but your IP until you respond. The ISP can’t legally give out your personal info to the claimant, just pass the notice to you.
And even if they do give the account holder’s information to the requesting law firm, courts have ruled that an IP isn’t a person and if you want to bring suit against a person, the rights holder needs to identify an individual responsible. Lawyers know this and don’t generally take cases like that, too.
