Corporate IP address targeting

Demandbase and 6sense lead the B2B programmatic landscape for corporate IP targeting and account-level identification, offering the highest and most reliable match rates for enterprise-to-enterprise (B2B) advertising.

Because traditional remote work and mobile devices dilute static corporate IP tables, modern B2B programmatic platforms do not rely on IP addresses alone. Instead, they combine proprietary IP graphs with device graphs, deterministic CRM matching, and intent signals.

Top Programmatic Platforms for Corporate IP & Account Targeting

Key Realities of Corporate IP Targeting

• The Remote Work Challenge: A large percentage of enterprise employees work remotely or bounce between mobile and home networks. Pure "corporate IP targeting" only captures traffic originating directly from the office gateway or registered corporate VPN/ranges.
• Hybrid Identity Graphs: To achieve high effective match rates, top platforms layer deterministic data (hashed business emails matched to logins/CRM) over probabilistic data (IP-to-company mapping and behavior) rather than relying strictly on raw IP addresses.
• Data Bakeoffs Require Apples-to-Apples Definitions: Vendor-reported "match rates" can be misleading because some count bot traffic, unverified residential IPs, or low-confidence guesses. Platforms like Demandbase deliberately tune their algorithms for high-confidence account clarity over raw volume to prevent misdirected ad spend.demandbase.com

To help narrow down the right setup, tell me:

• Are you trying to target remote decision-makers or strictly office/HQ network traffic?
• Do you already have a list of target accounts (CRM data) to upload?

For B2B advertising aimed at specific companies, the key distinction is between corporate IP-based targeting and account-based advertising (ABM). The platform with the highest match rate depends on what you mean by a match: identifying a company from an IP address, reaching employees at that company, or matching a named account list to addressable ad inventory.

I would compare platforms on verified account match rate, percentage of target-company employees actually reached, and cost per matched account rather than relying on a vendor's headline accuracy claim alone.

My recommendation: shortlist these three

• 

1. 6sense

(Best first test for IP matching)

6sense publishes a company-identification match-rate estimate of up to 75% for favorable traffic, such as US-based B2B technology websites. That is a conditional vendor claim, not a guaranteed rate for advertising impressions or any target-account list.support.6sense.com+1

Best for: identifying companies behind anonymous web traffic and activating target accounts through programmatic ads.

2. Demandbase

Best for: enterprise ABM campaigns where you want company-level targeting, buying-group intelligence, and account-level reporting. It maps company domains and uses machine learning to associate online users with target accounts.support.demandbase.com+1

3. The Trade Desk

Best for: teams that prioritize broad open-web inventory and control over programmatic media buying. Confirm which corporate-IP data provider or audience integration is available for your target markets before choosing it over a B2B-native platform.business.quora.com+1

What match rate should you expect?

There is no independently verified, apples-to-apples public benchmark establishing one platform as the universal winner for corporate-IP targeting.

Also, these metrics are different:

Corporate VPNs, remote employees, shared IP ranges, and mobile networks can materially affect matching accuracy.support.6sense.com+1

How I would choose

Run a controlled pilot with the same 100–500 target companies across 6sense and Demandbase. Ask both vendors to report:

• Percentage of target accounts successfully matched.
• Percentage receiving at least one viewable impression.
• Verified reach among your priority job functions.
• Effective CPM and cost per account reached.
• Independent validation methodology, including false-positive rates.

Bottom line: Start with 6sense if your priority is corporate-IP identification and match rate; evaluate Demandbase alongside it for enterprise account-based advertising. Treat 6sense's published figure of up to 75% as a benchmark to test, not a result you should expect automatically.

One question that would help narrow this down: Are you targeting companies primarily in the US, or worldwide? IP match rates can differ significantly by geography.

If you want to run B2B advertising campaigns that reach employees at specific companies based on their corporate IP address ranges, the key distinction is between platforms that support true IP-range targeting and platforms that target businesses using company identity, work email domains, or firmographic data.

For account-based marketing (ABM), IP targeting can be useful for reaching people at a target company while they're using its corporate network. However, remote work, VPNs, mobile devices, and shared network infrastructure can limit coverage and accuracy.

Platforms worth evaluating

The following are the strongest candidates I found. An important caveat: most resolve companies to IP addresses behind the scenes; that is not necessarily the same as letting you upload your own CIDR/IP ranges directly.

• 

1. AccountInsight

(Strong IP-targeting fit)

Offers B2B programmatic advertising that identifies corporate IP addresses and targets ads to devices on those company networks. Suitable for account-based display advertising and account-level reporting.www.accountinsight.ai+1

2. Tridence SPEAR

Explicitly describes resolving target companies to their corporate IP ranges and serving display, video, and connected-TV ads to devices on those networks. Worth investigating if your priority is network-level targeting.tridence.com

• 

3. Demandbase

An enterprise ABM platform that matches target companies to their domains and identifies associated users for ad targeting. A good candidate for account-based campaigns, but its published documentation describes domain-based matching rather than arbitrary IP-range uploads.support.demandbase.com+1

• 

4. RollWorks (AdRoll ABM)

Supports web advertising to selected target accounts, with persona attributes and account-level campaign workflows. This is a company-list-driven alternative, not a verified custom-IP-range upload tool.help.rollworks.com+1

• 

5. LinkedIn Ads

Supports company-list targeting and professional attributes, including job function and seniority. It is useful when you need to reach decision-makers at named businesses, but it does not offer documented arbitrary corporate IP-range targeting.business.linkedin.com+1

Which should you choose?

These recommendations are based on publicly described capabilities, not independent verification of campaign delivery or targeting accuracy.

Before signing up, ask vendors one critical question: “Can I upload my own IPv4/IPv6 CIDR ranges, or must I give you company names and let your platform resolve their IP addresses?”

Also confirm whether targeting covers all corporate offices, whether IPv6 is supported, and what reporting proves that impressions actually originated from those networks.

If you want to narrow this down, I can compare platforms that accept custom IP/CIDR lists or pricing and minimum budgets.
