Most dogs are happy to see new people, but even the most outgoing pooch can be overwhelmed by a large company of visitors. A stressed out dog can be a danger to your guests, especially rambunctious and curious children. If you're having a large bunch of people over for company, especially if that bunch includes children, it may be better to contain your dog.
Designate a room as your dog's "safe" spot, or keep his crate handy. If he shows signs of becoming stressed out, put him in his crate, in a quiet room, or just in a quiet, darkened room by himself. By removing him from the activity, you'll be giving him a chance to calm down, and will prevent any accidental, or deliberate injuries, to your dog and your company.
