What is Network Type; how does it differ from IP Reputation?
Short answer
Network Type is the classification that shows what kind of network an IP address belongs to: a data center, a CDN, a verified bot, an anonymizer or an end-user network. It differs from IP Reputation in that it looks not at whether the address has been abused in the past, but at where it belongs; a data center address does not have to be bad. TR7 recognizes 5 categories (Datacenter, CDN, Verified Bot, Anonymizer (VPN / Proxy / Tor), End User) and 21 groups (e.g. Amazon AWS, Hetzner, Tor Exit Node, Mobile / CGNAT); each group is bound to a single category, and an address that is not in the classification data falls into no category. This classification is used in the Network Type Category and Network Type Group conditions in the Load Balancer, in the Network Type Group Control block in L7 DDoS Protection, in the IP Lookup result and on the Distribution tab of IP Intelligence & Reputation.
Where It Is Used in TR7
| Where | Field / label | What for |
|---|---|---|
| Load Balancer → Conditions | Network Type Category, Network Type Group | An action or routing based on the network type |
| Bot/DDoS Management → L7 DDoS Protection | Network Type Group Control (including Exempt Network Groups) | A limit or a direct action on the requests and connections coming from a network group |
| Bot/DDoS Management → Bot Protection → Factors | Datacenter Ip, Tor Exit | The contribution of the network type to the bot score |
| Bot/DDoS → Event Logs | Network Type | The network group of the source |
| Settings → General Settings → IP Intelligence & Reputation → IP Lookup | The Network Type row | The group and the category of the address |
| IP Intelligence & Reputation → Distribution | Blacklist by Network Type, Network Category | The distribution of the blacklisted addresses by network type |
| Log profile and smart variable fields | %NETTYPE_GROUP, %NETTYPE_CATEGORY | Writing the network type to the log or to another field |
Difference from IP Reputation
| Network Type | IP Reputation | |
|---|---|---|
| Question it asks | What kind of network does the address belong to? | Has the address been reported for abuse? |
| Values | 5 categories, 21 groups (e.g. Datacenter, Tor Exit Node) | Reputation categories (e.g. Brute-Force, Port Scan, Open Proxy, VPN IP) |
| Source | The network type database on the device | The IP reputation database, External sources and the manually added Blacklist content |
| Condition / protection in TR7 | Network Type Category / group conditions, Network Type Group Control | The Blacklist IP Category condition, IP Reputation Protection |
Common Misconceptions
- "Datacenter traffic is malicious." Legitimate traffic such as API clients, monitoring systems and company egress traffic also comes from data centers; the network type alone is not a reason for blocking.
- "Network Type and reputation are the same list." One shows the type of the network, the other the abuse history of the address; an address can be both in Datacenter and in a reputation category.
- "Every address falls into a category." An address that is not in the classification data falls into no category; for this address, the condition is not met.
Using the network type and reputation data together: How do I recognize and handle Tor exit nodes, VPN/proxy addresses and data center (cloud/hosting) IPs separately?
