S03-I2: Yes
Rationale
An independent private-IPv4 deployment can enable i2np.allowLocal and supply fresh RouterInfos, numeric NTCP2 contacts and destination keys locally. The NTCP2 address checks explicitly admit local addresses under that setting. No public address allocation is required within this boundary.
Assessment method
Documentary analysis
Source context
Primary specification / explicit profile inference
Outstanding qualification
Configure all routers consistently, local network/bootstrap and floodfill roles, allowLocal, keys and clock; disable external reseed/DNS. Validate fresh private RouterInfo admission and end-to-end tunnels. Full isolated deployment untested.
