No, If your system has a static address (and a server should have one), you don't need SLAAC or Router Solicitation. You just need to set the address: ifconfig_bce0_ipv6="inet6 2607:f758:2280::n/64" and ipv6_defaultrouter="Router address". Netmasks are obsolete everywhere and really should not be used. CIDR addressing has been the standard for a quarter century. Netmasks really should not be used for either IPv4 or IPv6. I am unable to translate the statement from the provider with certainty. I am guessing that the /64 2607:f758:2280::/64 is used by their router with 2607:f758:2280::4 as the address on their router(s). The remainder of the /56 is yours but I could not swear to that. You will probably want more than one /64 for different purposes. Other than externally accessible servers, you should put systems in a different /64 and spread them at random around that space if they are statically addressed. (I don't recommend for or against statically addressing, though.) -- Kevin Oberman, Network Engineer, Retired E-mail: rkober...@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683 _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
