On my OpenBSD machine i have several pseudo interfaces for vlan that looks like

vlan3: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        lladdr 00:04:e2:c5:02:2b
        vlan: 3 parent interface: sk0
        groups: vlan 
        inet6 fe80::204:e2ff:fec5:22b%vlan3 prefixlen 64 scopeid 0xa
        inet 10.0.172.253 netmask 0xffffff00 broadcast 10.0.172.255

These interfaces remained from previous sysadmin.

There are no /etc/hostname. files for it, so i'm just wondering where does it come from?

The proper way of setting up vlan's is using /etc/hostname.vlan1 (replacing 1 with whatever number of course) but technically, I suppose the previous admin could have written it into the /etc/netstart file which itself, looks for /etc/hostname.$if. I doubt though anyone would go and put it in there.

I know it's a longshot, but is it at all possible that the machine simply hasn't been rebooted, and these vlans were created on the command line, and there never was anything setup to ensure they'd be recreated on reboot?
