Hundreds of the same IP Address in survey

Question

In my business we have surveys about corporations (kinda like yelp).

When we looked at the IP Addresses of those who voted, there where several hundred from the same 4 IP Addresses.

I looked those up on a "whois" service and they were all registered to the company that was being voted on. That's just them voting themselfs up basically or am I crazy?

could there be other explanations? – user2037559 Jul 19 '17 at 10:05 — user2037559, Jul 19 '17 at 10:05

Users in corporations typically wont have unique IP addresses, they will share a public IP address by using a system known as Network Address Translation - just google it for more details.

The fact you are seeing four IP addresses just mean that company uses multiple IP addresses, maybe due to different physical locations

You do not need to be in corporations. Having a smartphone and browsing from there means most of the time going through some phone provide CGN and hence sharing an IP with many other owners of a smartphone with the same provider. – Patrick Mevzek Jul 27 '17 at 21:07

If that company have more then 1 branch, then its clear each branch have lot of users in it,each branch have one public IP with ISP and people are voting under that 4 Public IPs as you can only see public IPs not there LAN IPs.

Lets say they have 4 branches

1) 4 Branches have 4 Public IPs register under that company via ISP.

2) people start voting under that 4 Public IPs and you can only see several hundreds votes under 4 IPs address.
