How to Handle Subdomains with Irrelevant Content

[PapercutInteractive]

Hi Everyone,

My company is currently doing a redesign for a website and in the process of planning their 301 redirect strategy, I ran across several subdomains that aren't set up and are pointing to content on another website. The site is on a server that has a dedicated IP address that is shared with the other site. What should we do with these subdomains? Is it okay to 301 them to the homepage of the new site, even though the content is from another site? Should we try to set them up to go to the 404 page on the new site?

Do they have authority? If not, feel free to 404 or 301 redirect to new homepage.

If yes, that might affect ranking of the sites that they currently link to.
