What Is IP Targeting?
An advertising technique that serves ads to devices associated with a specific company's IP addresses.
IP targeting is an advertising technique that identifies and serves ads to devices connected to a specific company's IP address range. It is one of the primary mechanisms behind account-based advertising, allowing marketers to reach employees of target companies as they browse the web without requiring personally identifiable information.
The process works by matching corporate IP addresses to company names. When an employee at a target account browses a website that serves programmatic ads, the ad platform recognizes the IP address as belonging to that company and serves an account-targeted ad instead of a generic one. This happens in real time through the programmatic bidding process.
IP targeting accuracy depends on the quality of the IP-to-company mapping database. Major ABM platforms maintain their own databases or license them from providers. Accuracy is generally strong for large enterprises with dedicated IP ranges but weaker for smaller companies that share IP addresses through ISPs or cloud services. Remote work has further complicated accuracy, as employees working from home use residential IPs that are harder to associate with their employer.
The rise of remote work has been the biggest challenge for IP targeting. When most employees worked from office locations with known corporate IP ranges, targeting accuracy was high. With distributed workforces, many impressions go undelivered because the platform cannot identify home network IPs. ABM platforms have responded by supplementing IP targeting with cookie-based and email-based matching approaches.
Best practices for IP targeting include focusing on larger companies where IP databases are more accurate, supplementing with other targeting methods (LinkedIn, email match, cookie-based) for broader coverage, monitoring viewability and frequency to avoid wasting impressions, and using IP targeting as one channel within a multi-channel ABM strategy rather than relying on it exclusively.
Privacy regulations affect IP targeting. GDPR and similar frameworks classify IP addresses as personal data in some contexts. Ensure your ABM advertising vendor complies with applicable privacy laws and provides transparency about their data sources and targeting methodology.
IP Targeting in Practice
An ABM team buys IP-targeted display through 6sense to reach their 400 named accounts. The platform resolves company-level IP ranges from public databases and serves ads to anyone browsing from a corporate network of a target account. Bank of America employees browsing The Wall Street Journal see the vendor's ads; employees of non-target companies see nothing. The team measures account-level reach and pairs it with cookie-based retargeting to extend coverage to remote employees. Another example: a B2B SaaS vendor uses IP targeting for a field marketing event in San Francisco. They serve ads geofenced to the buildings of their 30 target accounts in the area for the week leading up to the event. CFO meetings booked from the event run 40% acceptance versus a typical 22% on cold outreach. The CFO has been seeing the vendor's name on his office building's WiFi all week before the rep emails.
The Most Common Mistake Teams Make
Relying on IP targeting alone in a hybrid-work world. IP-targeted ads reach buyers in the office, but in 2026 a meaningful share of B2B buyers spend most of their week working remotely from home WiFi networks that don't resolve to the target account. IP targeting that worked at 90% coverage in 2019 might cover 50% to 60% in 2026. The fix is to pair IP with cookie-based or LinkedIn person-level targeting to catch remote workers.
What to Measure
Coverage rate against the named account list, measured as the share of accounts with at least one resolved impression in the prior 30 days. Healthy programs hit 85%+ on accounts with significant office presence. For remote-heavy ICP, pair with LinkedIn person-level coverage to fill the gaps.
Tool Landscape
6sense, Demandbase, and Terminus offer IP-targeted display as part of their ABM platforms. Madison Logic and RollWorks serve as standalone account-based ad delivery. LinkedIn Company Targeting covers person-level reach inside accounts and is often paired with IP for full coverage. DSPs (StackAdapt, MNTN) handle account-targeted CTV and audio that complement display.
Frequently Asked Questions
How does IP targeting work for ABM?
IP targeting matches corporate IP addresses to company names. When an employee at a target account browses a website with programmatic ads, the platform recognizes the IP and serves an account-specific ad. It enables reaching target accounts without personal data.
How accurate is IP targeting?
Accuracy is strong for large enterprises with dedicated IP ranges (80-90%+) but drops for smaller companies and remote workers. The shift to remote work has reduced overall IP targeting effectiveness, pushing ABM platforms to supplement with cookie and email-based matching.
Does IP targeting still work with remote employees?
It is less effective for remote workers since home IPs are harder to map to employers. ABM platforms now combine IP targeting with cookie matching, email-based audiences, and LinkedIn targeting to maintain account-level reach in hybrid work environments.
How does IP targeting work technically?
Public IP-to-company databases (maintained by vendors like Digital Element, Dun & Bradstreet, and the ABM platforms themselves) map corporate IP ranges to specific companies. When a browser request comes from an IP in a target company's range, the ad is served. Match accuracy is highest for large enterprises with dedicated networks and lower for smaller companies that share IPs with neighbors.
What's the difference between IP targeting and account-based advertising?
IP targeting is one technical method for account-based ad delivery. ABA is the broader category, which can also use cookie graphs, LinkedIn company matching, or CRM-list-based targeting. Most ABA programs combine multiple delivery methods because no single method covers every buyer.
Does IP targeting still work with remote work?
Coverage has dropped meaningfully. Most teams now pair IP targeting with cookie-based identity resolution and LinkedIn person-level reach to catch buyers working from home. Pure IP targeting probably covers 50% to 65% of buyers at most B2B target accounts in 2026, down from 85%+ pre-2020.
