FNIS is the autonomous system for Fidelity National Information Services, Inc.

What it's used for

• The address space carries corporate infrastructure for financial services, evidenced by netnames like FIS-GLOBAL, FIS-IDDIS, and UK-FISEMEA-20131129, and reverse DNS entries such as shoppingcard.auspost.fisprepaid.com and nat-199-200-26-254.fnfis.com.
• The AS announces 25344 IPv4 addresses across 67 prefixes with 10 observed neighbours, a ratio consistent with a large internal corporate estate rather than a transit or access provider.
