The traits of all those sweeps were very similar:

- the source port of all probes was 22
- all probes within one sweep had the same IP ID (*)
- lost/filtered probes were not retried
- the sweeps were pretty fast, hundreds of addresses in few seconds
- no actual i/o was done

(*) With 1 exception that had a TTL different from other logged probes
in the sweep as well.

This appears to be the work of the synscan tool. Did the common IP IDs
happen to have a value of 39426?
