eir Mobile and GoMo now support IPv4v6 and IPv6
APNs data.myeirmobile.ie and broadband.myeirmobile.ie now also support IPv4v6 and IPv6 connections. To manually update a phone to also have IPv6 connectivity edit the APN protocol to "IPv6" or "IPv4/IPv6". Most Android phones let the APN protocol be edited. Apple iOS phones do not let this setting be edited by the user. Existing phones of all types will continue to request IPv4 connections until their software/configuration settings have been updated to request IPv4v6 or IPv6. In all cases phones will continue to have IPv4 connectivity even when the requested APN protocol is "IPv6". More technical details IPv6 end-to-end traffic bypasses the network NAT. The IPv6 DNS servers advertised by the eir network generate DNS64 AAAA responses to DNS queries made over IPv6 transport. i.e. DNS IPv6 AAAA records are synthesised for FQDNs that only have IPv4 A records. IPv4v6 is dual stack, the UE (User Equipment e.g. a smartphone) requests both an IPv4 address and an
