Depending on your business use-case, sharing a pool of IPs can have detrimental impact on access. For example, you may find the prior users were doing unauthorized security scans, spamming email, or hosting proxies. i.e. if you get an IP block with a bad reputation, than you may find running a mail or VoIP server problematic.
