fec0 is the site-local addresses. Nobody should be assigning addresses in that range since they are made automatically. Using site-local addresses makes sense for single subnet network like most home networks.

It is made out of two halves. fc00::/8 and fd00::/8 fc00::/8 is reserved. People are only allowed to use fd00::/8 > fec0 is the site-local addresses. Nobody should be assigning addresses in that range since they are made automatically. Using site-local addresses makes sense for single subnet network like most home networks. None of my adapters have automatic fec0 addresses, they only have global and fe80. So can you elaborate on that?
- ianburrell 3y agoI don't know that about ULA range. I got fe80 and fec0 confused. It looks like the latter is the deprecated site-local range. It is unlikely that will be reassigned, but lots of people said the same with IPv4 and got burned. It is safer to use ULA.
- Dylan16807 3y agoAh, yeah, fe80 is automatic but it's link-local so you can't do very much with it.
