Internet Engineering Task Force (IETF) R. Koodli Request for Comments: 6342 Cisco Systems Obsoletes: 6312 August 2011 Category: Informational ISSN: 2070-1721 Mobile Networks Considerations for IPv6 Deployment Abstract Mobile Internet access from smartphones and other mobile devices is accelerating the exhaustion of IPv4 addresses. IPv6 is widely seen as crucial for the continued operation and growth of the Internet, and in particular, it is critical in mobile networks. This document discusses the issues that arise when deploying IPv6 in mobile networks. Hence, this document can be a useful reference for service providers and network designers. RFC Editor Note This document obsoletes RFC 6312. Due to a publishing error, RFC 6312 contains the incorrect RFC number in its header. This document corrects that error with a new RFC number. The specification herein is otherwise unchanged with respect to RFC 6312. Status of This Memo This document is not an Internet Standards Track specification; it is published for informational purposes. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Not all documents approved by the IESG are a candidate for any level of Internet Standard; see Section 2 of RFC 5741.

Introduction The dramatic growth of the Mobile Internet is accelerating the exhaustion of the available IPv4 addresses. It is widely accepted that IPv6 is necessary for the continued operation and growth of the Internet in general and of the Mobile Internet in particular. While IPv6 brings many benefits, certain unique challenges arise when deploying it in mobile networks. This document describes such challenges and outlines the applicability of the existing IPv6 deployment solutions. As such, it can be a useful reference document for service providers as well as network designers. This document does not propose any new protocols or suggest new protocol specification work. The primary considerations that we address in this document on IPv6 deployment in mobile networks are: o Public and Private IPv4 address exhaustion and implications to mobile network deployment architecture; Koodli Informational [Page 2] RFC 6342 IPv6 in Mobile Networks August 2011 o Placement of Network Address Translation (NAT) functionality and its implications; o IPv6-only deployment considerations and roaming implications; and o Fixed-Mobile Convergence and implications to overall architecture. In the following sections, we discuss each of these in detail. For the most part, we assume the Third Generation Partnership Project (3GPP) 3G and 4G network architectures specified in [3GPP.3G] andShow full document text
