Domain Contexts

This Shows information relating to the IP addresses that have been seen sending emails for the domain.

The score is a reputation value, similar to the one associated with the domain, but refers to the reputation of the sender’s IP address. It is important to remember that the IP addresses will cover a broad range of reputation, from very good to exceptionally poor and the sender’s IP reputation may not be strictly related to the domain itself.

Hostnames listed

Spamhaus assesses the reputation of each domain across several dimensions. Each dimension is a container which we associate signals with. For example, if we receive a signal indicating a bot infection, we will modify the malware dimension while if we have signals relating to the emails sent by the domain reaching our spamtraps, we will alter the smtp dimension.

The main supported dimensions are:

• smtp: Reputation in the SMTP area
• identity: Reputation of the identity of the domain. (Owner, registrar and more)
• infra: Reputation of the infrastructure of the domain. (NS, hosts, etc.)
• malware: Reputation of the domain affected by malware, bots and the distribution of such threats
• human: The human reputation for a domain, accounting for operations and false positive fallouts. This dimension represents the opinion of Spamhaus researchers about the domain.
• 3rdparty: Third parties reputation signals are added to this dimension.
