How Dynamic is the ISPs Address Space? Towards Internet-Wide DHCP Churn Estimation

IP address counts are typically used as a surrogate metric for the number of hosts in a network, as in the case of ISP rankings based on botnet infected addresses. However, due to effects of dynamic IP address allocation, such counts tend to overestimate the number of hosts, sometimes by an order of magnitude. In the literature, the rate at...

Towards Incentivizing ISPs To Mitigate Botnets

ISPs form a centralized point to control botnet infections. However, they do not have enough incentives to invest in mitigation of botnets. In this paper, we propose an approach based on comparative metrics to incentivize ISPs to mitigate botnets.
