As ISPs face IPv4 address scarcity they increasingly turn to network address translation
(NAT) to accommodate the address needs of their customers. Recently, ISPs have moved …

To mitigate IPv4 exhaustion, IPv6 provides expanded address space, and NAT allows a
single public IPv4 address to suffice for many devices assigned private IPv4 address space …

Given the increasing scarcity of IPv4 addresses, network operators are resorting to
measures to expand their address pool or prolong the life of existing addresses. One such …

Recent years have seen the rise of middleboxes, such as NATs, firewalls, or TCP
accelerators. Those middleboxes play an important role in today's Internet, and are now …

Recent research has shown that last-mile latency is a key network performance indicator
that contributes heavily to DNS lookup and page load times. Using a month-long dataset …

The usage of Network Address Translation (NAT) devices is common among end users,
organizations, and Internet Service Providers. NAT provides anonymity for users within an …

The Internet measurement community is increasingly sensitive to the privacy implications of
both active and passive measurement. Research into the drawbacks of network data …

Middleboxes are pervasive in today's Internet as they are deployed for an increasing
number of reasons. An example is the network address translation (NAT), one of the first task …

Carrier Grade NAT (CGN) mechanisms enable ISPs to share a single IPv4 address across
multiple customers, thus offering an immediate solution to the IPv4 address scarcity problem …

In this dissertation, we evaluate the potential of unsolicited Internet traffic, called Internet
Background Radiation (IBR), to provide insights into address space usage and network …
