System Management
Basic System Configuration Guide 233
On SR OS routers, it is possible to query the DNS server for IPv6 addresses. By default the
DNS names are queried for A-records only (address-preference is IPv4-only). If the address-
preference is set to IPv6 first, the DNS server will be queried for AAAA-records first, and if
there is no successful reply, then A-records.
