Anomalous Internet Traffic

If you've observed anomalous Internet traffic associated with our address space, we list below more information on research we're conducting, what you might expect to see, and how to opt out.

DNS queries to DNS servers for DNS records within the dns-laboratory.internet-measurement.cs.byu.edu zone

We are conducting experiments to characterize DNS server behavior, particularly with respect to open resolver behavior. The custom queries we issue to a resolver supporting recursive DNS queries from our address space force it to in turn issue queries to the servers authoritative for dns-laboratory.internet-measurement.cs.byu.edu, which are under our control.

DNS queries to authoritative servers for DNS records that don't exist

We are conducting experiments to understand the handling of negative DNS responses by DNS authoritative servers, which requires us to issue queries to servers for names or types that don't exist within the DNS zone for which the servers are authoritative.

DNS queries to resolvers for DNS records within the resolver-select.internet-measurement.cs.byu.edu zone

We are conducting experiments to characterize resolver behavior with respect to DNS authoritative server selection. The custom queries we issue to the resolver force it to in turn issue queries to the servers authoritative for resolver-select.internet-measurement.cs.byu.edu, which are specially configured and under our control.

DNS queries to resolvers for DNS records for non-existent domain names within select domains

We are conducting experiments to characterize resolver behavior with respect to DNS authoritative server selection and proximity to resolvers. Issuing queries for DNS records that don't exist help us to better understand that behavior.
