What it is
LinkedIn's anti-abuse system has three priors when evaluating an account: who, where, and how. The 'where' is the IP. Most LinkedIn automation tools fail this check by routing every customer through shared cloud or rotating residential IPs — both of which LinkedIn flags inside weeks.
Infonet operates its own residential IP infrastructure. Every profile gets a dedicated home IP that's geographically matched to the profile's listed location. Never shared across customers. Never rotated. The kind of IP a real user would actually log in from.
Why dedicated and not shared
Most 'residential proxy' tools route every customer's traffic through a rotating pool of IPs shared across thousands of users. The IP that LinkedIn sees from your account this hour might have been used to spam Instagram an hour ago.
LinkedIn's IP reputation database tracks behavior across user sessions. A residential IP with five different LinkedIn accounts logging in from it over a week is statistically as suspicious as a datacenter IP.
Dedicated home IPs solve both problems: one IP per Infonet customer, one LinkedIn account per IP, one consistent residential signature.
Where the IPs come from
Infonet operates its own residential IP infrastructure (InfoProxy) — a fleet of devices distributed across residential ISP connections in major metros. We own the hardware and the IP allocation, so we control the supply.
Compare: most tools resell IPs from third-party residential proxy networks (Bright Data, Smartproxy, Oxylabs). Those networks have legitimate uses but their pool quality varies wildly because the supply is crowdsourced from end-user devices.

Geographic matching
Each LinkedIn profile is assigned an IP from the same metro area as the profile's listed location. A San Francisco-based profile gets a Bay Area home IP. A London-based profile gets a Greater London IP.
This matters because LinkedIn cross-checks profile location against login geography. Mismatches trigger verification gates and flag the account.
The geographic pool is large enough to support most US, EU, UK, and major APAC metros. A few specific cities (e.g., Bermuda, Reykjavík) require advance notice.
Reliability
Dedicated home IPs have a small failure mode: residential ISPs occasionally drop the connection. Infonet auto-fails-over to a hot-spare IP in the same metro within 60 seconds, and re-claims the original when it comes back.
Net effect: 99.7% in-region IP uptime per profile, measured across our customer fleet in 2026.
Fail-over is invisible to the LinkedIn account. The account's session persists across the IP swap.
What this means for your account
Profiles running on dedicated home IPs see acceptance rates 8–12 percentage points higher than the same profile run on shared cloud IPs (we A/B tested this on willing customers in 2025).
Restrictions are dramatically less common. The Infonet customer fleet's restriction rate is effectively 0% with default safe-mode pacing.
Recovery from rare restrictions is faster too — the dedicated IP doesn't carry stale flags from other accounts.
