Unclassified ARIN
Summary
Fannie Mae
enterprise legacy
FANNIEMAE is the Federal National Mortgage Association — Fannie Mae, the US government-sponsored enterprise that buys mortgages from lenders and packages them into securities. It is a shareholder-owned corporation under federal conservatorship, not a government agency, and its network reads as pure enterprise.
What it's used for
RIS sees 41 IPv4 prefixes, 10,496 addresses, no IPv6 and only 2 observed neighbours. The prefix count is high relative to the address count because the inventory is almost entirely /24s, drawn from two blocks: 167.133.0.0 and 198.204.128.0 upward. Every prefix in the pack is registered to Fannie Mae, under two netnames — MORNET and FNMA-CNETS. Registrant and origin agree throughout, so there is no third-party space and nothing broker-shaped in the inventory, however long the prefix list looks.
Notable
Forty-one prefixes announced to two neighbours is the shape that matters. A network that peers with two ASes is buying transit, not selling it, no matter how many routes it originates. What produces the long /24 list is not connectivity ambition but segmentation: a financial institution that keeps distinct, separately-routable public blocks for its data centres, its DMZs, and its lender-facing interfaces, because counterparties, regulators and firewall policies allowlist by source address and a stable per-function /24 is what makes that possible.
Interesting
The MORNET netname is corporate archaeology in the registry. Fannie Mae's lender-facing electronic delivery network carried that name for years, and the address blocks that served it still wear it — an internal system name outliving the system, which is a common fate for netnames and a reminder to read the org field rather than the label.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 454 networks and 1,847 prefixes, as published 2026-11-11. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
