Demandbase holds a narrow lead over 6sense for identifying accounts and mapping corporate IP ranges to intent data. StackAdapt serves as the usual answer when buyers seek programmatic platforms specifically for high match rates.
Because corporate networks, remote workforces, and dynamic cloud hosting make raw IP matching difficult, ABM-native (Account-Based Marketing) platforms perform better than generic demand-side platforms (DSPs) by layering proprietary graph data over IP addresses.
Massive open-web inventory scale utilizing third-party B2B data graph providers (like LiveRamp or Bombora).
Large-scale custom programmatic execution when you bring your own target account IP/list segments.
Remote Work Dilution: Traditional corporate IP targeting suffers when target decision-makers work from home. Platforms like Demandbase and 6sense mitigate this by combining corporate IP recognition with device graphs, b-to-b cookie spaces, and login identity signals.
For targeting specific companies with personalized programmatic ads, I’d put Demandbase at the top of the shortlist for enterprise-scale account targeting, with AdRoll ABM as a strong alternative if your primary goal is advertising reach and dynamic ad personalization.
One important distinction: the platform with the highest corporate IP match rate is not necessarily the one that delivers the most impressions to employees at your target companies. Public information does not establish a reliable, independently verified winner on IP match rate alone.
The leading platforms to evaluate
1. Demandbase — Best starting point for enterprise ABM
Uses company-domain mapping and machine learning to associate online users with target accounts. Its advertising platform processes approximately 20 billion domain signals daily, according to its documentation.
Best for large target-account lists, complex corporate structures, and account-level campaign measurement.

2. AdRoll ABM — Best for dynamic company-specific ad creative
Supports company-level personalization, such as inserting a target company's name into display ads. Its matching inputs include proprietary IP data, reverse-IP lookup through KickFire, and data partnerships.
Best when the creative itself needs to change based on the company being reached.

3. 6sense — Best for intent-driven targeting
Worth evaluating if you want to prioritize companies showing buying intent and coordinate advertising with sales outreach, rather than optimize solely for corporate IP matching.

4. LinkedIn Matched Audiences — Best for reaching verified professional audiences
Upload company names or domains to target organizations on LinkedIn, or use matched contact lists. This is a useful alternative when professional identity matters more than reaching people across the open web.

How to determine which has the highest match rate
Ask each vendor to run the same test against your actual target-account list. Compare these metrics separately:
Metric
What to measure
Account match rate
Percentage of target companies successfully resolved
IP-to-company accuracy
Percentage of resolved IPs correctly attributed to the intended company
Reachable account rate
Percentage of target companies with enough identifiable users and ad inventory to serve impressions
Effective reach
Number of distinct target companies and employees actually reached
Match freshness
How quickly IP and company associations are refreshed
Corporate VPNs, remote employees, shared networks, and subsidiaries can all complicate IP-based attribution. A vendor may match many IP addresses without reliably reaching the specific people you want.
My recommendation: Start with Demandbase and AdRoll ABM, and make the final choice contingent on a head-to-head test. Do not accept a headline match-rate claim without the denominator, measurement method, and independent validation.
One question that would help narrow this down: Are you targeting companies across the open web (display/programmatic ads), or are you primarily trying to reach employees of named companies on LinkedIn? The best platform can differ substantially between those two use cases.
Yes. If by “target businesses using their corporate IP address ranges” you mean identify traffic coming from an organization's known IP space and serve ads to people associated with that company, there are B2B/ABM platforms that support this, although the implementation varies.
Platform
Corporate-IP-based targeting
How it works
Demandbase
Yes / core capability
Its identity system uses IP and other signals to identify companies; its B2B DSP can then deliver programmatic advertising to account audiences.
LinkedIn Ads
Indirectly / automatically
LinkedIn says it can derive a member's company from their public IP when company information isn't available, using an IP-to-company model. You can then use Company/Account Targeting, but you don't upload arbitrary corporate CIDR ranges directly.
Terminus
Account-based, with IP/identity signals
Terminus supports account-based advertising and can sync target-account audiences into LinkedIn; its approach is more account/identity based than “enter these IP ranges into an ad campaign.”
6sense
Account/IP identification
6sense is another ABM platform built around identifying anonymous company traffic and activating account audiences across advertising channels.
RollWorks
Account-based advertising
Targets named accounts using its B2B identity/account data rather than requiring you to manually provide IP ranges.
The important distinction
If you specifically want:
“I have 203.0.113.0/24 belonging to Company X; show my ads to users whose current public IP falls within that CIDR.”
that's a much narrower requirement than ordinary B2B “company targeting.”
For example, LinkedIn's documentation explicitly describes using public IP to infer the member's company, but its advertiser-facing targeting interface is based on companies, professional attributes, and matched audiences—not a field where you paste corporate CIDRs.
Demandbase is the closest fit to the underlying mechanism you're describing. Its current documentation says its account-identification system uses IP addresses among its identification signals, while its advertising product is a B2B DSP designed to reach target accounts across the web.
One caveat: corporate IP targeting is inherently imperfect. VPNs, cloud/SaaS traffic, remote workers, mobile networks, NAT, shared infrastructure, and subsidiaries can make an IP-to-company mapping probabilistic rather than deterministic. Demandbase itself describes its identification as probabilistic and notes difficulties when parent and subsidiary companies share IT infrastructure.
If you tell me whether you need (a) exact CIDR/IP-range upload, (b) targeting a list of named companies, or (c) identifying a company from IP and then retargeting it, I can narrow this to the platforms that actually support that workflow and compare pricing, minimum spend, and geographic coverage.
Mainstream consumer/social ad networks (like Meta or Google Ads) do not natively let you upload a raw list of corporate IP netblocks/ranges to target. Instead, they rely on logged-in user data, cookies, or general geographic location.
The top platforms that specialize in or support corporate IP and account-level network targeting include:
Demandbase Advertising : A leading ABM platform with its own proprietary B2B DSP. It maps corporate IP addresses and firmographic data so you can target specific account lists, headquarters, or office locations down to the network level.[](]()](]()]()
RollWorks : Part of NextRoll, RollWorks offers robust B2B programmatic advertising capabilities. It allows marketers to upload target account lists, which are then matched against proprietary corporate IP and device graph databases to serve display ads to employees on those corporate networks.[](https://www.heysid.com/resources/ip-targeting-for-b2b-how-it-works-and-when-to-use-it)
B2B Programmatic DSPs (e.g., The Trade Desk via custom B2B data graphs) : If you work with enterprise-grade programmatic DSPs like The Trade Desk , you can ingest B2B data segments (from providers like LiveRamp, Dun & Bradstreet, or Bombora) that map directly to company IP ranges or firmographic company profiles.
LinkedIn Ads (Indirect Alternative) : While LinkedIn does not let you target by IP address, it is the primary alternative for B2B digital targeting. Instead of network IPs, it targets the company name/domain directly through deterministic login data (e.g., targeting all employees at a specific company size, industry, or named account list).
Key Considerations Before You Launch:
The Remote Work Challenge: Relying strictly on static corporate office IP ranges means you will miss employees who are working remotely from residential or dynamic IP connections . Modern ABM platforms (like Demandbase or RollWorks) compensate for this by blending IP targeting with device graphs, cookie-less graph data, and contact-level matching.
