Wing Status: Experimental Stream: Independent Date: October 2016 Mailbox: brandon.williams@akamai.com, mohamed.boucadair@orange.com, dwing-ietf@fuggles.com Pages: 20 Characters: 48381 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-williams-exp-tcp-host-id-opt-08.txt URL: https://www.rfc-editor.org/info/rfc7974 DOI: http://dx.doi.org/10.17487/RFC7974 Recent RFCs have discussed issues with host identification in IP address-sharing systems, such as address/prefix-sharing devices and application-layer proxies. Potential solutions for revealing a host identifier in shared address deployments have also been discussed. This memo describes the design, deployment, and privacy considerations for one such solution in operational use on the Internet today that uses a TCP option to transmit a host identifier.
