The Co-operation WG may be interested in the following report of a reply by a European Commissioner to a European Parliamentary question about Carrier Grade NAT - not least because the reply refers to this WG by name. -------- Forwarded Message -------- Subject: (CGN) European Commission PQ response Date: Wed, 28 Jun 2017 08:37:47 +0000 From: Owen Bennett <owen at euroispa.org> To: DG-Euroispa cybersecurity <cybersecurity at euroispa.org> Dear EuroISPA Cybersecurity committee, The European Commission has published its answer to a recent European Parliament parliamentary question*concerning ISPs’ deployment of CGN (carrier-grade network access translation) and the so-called ‘going-dark’ problem.* To remind, ISPs are under increasing pressure from law enforcement with regard to their use of CGN technology – the fact of putting multiple users behind individual IP addresses is said to stifle law enforcement investigations of crimes with an online component. The Commission’s response to the parliamentary question is pertinent for EuroISPA in that it is one of the first times where the Institution has addressed the CGN matter in an official /on the record /capacity. As you will see, the Commission’s response falls short of calling for regulatory intervention to limit CGN deployment, and even goes as far as to label CGN deployment ‘unavoidable’. We will continue to monitor this matter at EU-level and keep members updated. Kind regards, Owen *** *Question of MEP Agnew (EFDD, UK), Carrier Grade Network Access Translation <http://www.europarl.europa.eu/sides/getDoc.do?pubRef=-%2f%2fEP%2f%2fTEXT%2bWQ%2bE-2017-001101%2b0%2bDOC%2bXML%2bV0%2f%2fEN&language=EN>, 17 February 2017* /[Europol recently held a meeting to discuss CGN technologies that have long been used by ISPs to delay the capex required to extend the current pool of IP addresses (CGN technologies are used by ISPs to share one single IP address among multiple subscribers at the same time)./ /Does the Commission agree that restricting the continued use of CGN, simply on the grounds that Europol finds it inconvenient to monitor, is a retrograde step and an unacceptable interference with current commercial practice and freedom of technological choice?]/ *Answer given by Commissioner Avramopoulos <http://www.europarl.europa.eu/sides/getAllAnswers.do?reference=E-2017-001101&language=EN> on behalf of the European Commission, 26 June 2017 * /[The Commission is aware that law enforcement authorities have raised certain concerns regarding the increasing use of Carrier-Grade Network Address Translation (CGN) technology. CGN enables a single Internet Protocol (IP) address to be shared by potentially thousands or hundreds of thousands of subscribers at the same time since there is not enough capacity under the current IP version 4 (IPv) to meet demand. This makes it technically very difficult for an internet service provider to identify an individual subscriber in response to legitimate requests from law enforcement authorities. Consequently, it is difficult to attribute crime and identify criminals using that particular IP address. Europol thus has legitimate concerns regarding CGN or other forms of address sharing, which may also have a negative impact on fraud detection or intrusion detection systems. They may also have other negative consequences, such as overall performance degradation of connections or even, in some cases, certain applications not working at all. / / / /The expedited deployment of IP version 6 (IPv6)//on a global scale and by all stakeholders would mitigate the problems and also offer new opportunities to service providers. In the short term, however, the use of IPv4 address-sharing is unavoidable, as there are still a significant number of users, services and applications that function only with IPv4. At the same time, the Commission is not aware of any proposals to restrict the continued use of CGN, but rather of efforts being made to raise awareness about the issue, share best practices and find ways to facilitate the attribution of crime. It intends to raise the issue to RIPE (Réseaux IP Européens) via its representative who is chairing RIPE's Cooperation Working Group.]/ *** *Owen Bennett* Policy Executive *EuroISPA - European Internet Services Providers Association * Rue du Commerce 124/5 - 1000 Brussels T: +32 (0)2 550 41 22 www.euroispa.org <http://www.euroispa.org/> Follow us on Twitter *@euroispa <https://twitter.com/euroispa>* *EuroISPA is the world's largest association of Internet Services Providers, representing over 2500 ISPs across Europe.* EU Transparency Register ID Number: 54437813115-56
