I'll be getting a prefix delegated to my UniFi USG, and I want the FreeBSD host to be able to assign addresses in that Prefix (not SLAAC, but static host part). I don't know that what I want is possible, but figured I'd ask. I.E. the router assigns 2001:aa:bb:cc::/64 as the prefix, an I want the host to wind up at 2001:aa:bb:cc::53:1 what do I need to do to make that happen? -- Larry Rosenman http://www.lerctr.org/~ler Phone: +1 214-642-9640 E-Mail: ler@lerctr.org US Mail: 5708 Sabbia Dr, Round Rock, TX 78665-2106 [-- Attachment #2 --] <html><head><meta http-equiv="Content-Type" content="text/html;
