Replace the hand-maintained _BLOCKED_NETWORKS CIDR list with a
default-deny check based on ipaddress.is_global (RFC 6890 semantics,
implemented by Python's stdlib). Also reject multicast explicitly —
is_global returns True for public multicast allocations, which are
not legitimate HTTP targets.
Only globally-routable cloud-fabric IPs need explicit exceptions; the
canonical list contains one entry today: Azure Wire Server
(168.63.129.16), an in-fabric service reachable from any Azure VM.
Coverage delta picked up automatically via is_global:
- Alibaba Cloud metadata (100.100.100.200, CGNAT)
- Legacy Oracle metadata (192.0.0.192, IETF Protocol Assignments)
- IPv4 documentation ranges (192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24)
- IPv4 reserved/future-use (240.0.0.0/4) and broadcast
- IPv6 documentation (2001:db8::/32)
Also fix two issues Greptile flagged:
- HTTP relative-redirect hops lost the original hostname because
_extract_redirect_url joined the Location against the rewritten
(IP-based) URL. Join against the pre-rewrite URL so the next hop's
Host header keeps the original hostname.
- Two unit tests performed real socket.getaddrinfo('localhost')
calls. Monkeypatch them.
Add coverage tests for every cloud-metadata IP from the canonical
SSRF dictionary (AWS/GCP/Azure/Alibaba/Oracle/DO/OpenStack) plus the
new multicast/reserved/documentation/broadcast ranges, and a
regression test for redirect-hostname preservation.

In total litellm runs 1000+ tests
[02/20/2025] Update:
To make it easier to contribute and map what behavior is tested,
we've started mapping the litellm directory in tests/test_litellm
This folder can only run mock tests.
