I'm not sure if these have a name, but on most computers I use the interface prefixes are usually:
- eth- : Ethernet/Wired
- wlan- : Wireless/WiFi
However, on my ASUS RT-N56U, I have the following:
- br0 : 'Ethernet' - Bridge?
- eth2 : 'Ethernet', IPv6 (where are 0 and 1?)
- eth3 : 'Ethernet', IPv4 (the one with my WAN IP)
- lo : 'Local Loopback' - What's this for?
- ra0 : 'Ethernet' - ?
- rai0 : 'Ethernet' - ?
Are there others? What do they mean?
