It allows dial-up Internet access like SLIP, but with an interesting twist. When an ST with KA9Q dials into MERIT, both ends automatically begin talking SLFP. But MERIT dynamically allocates the ST an IP address. The address assigned is different every time a connection is made. I'm told that there are plans to eventually allow for dynamic DNS updates: when a host connects and is told its IP address, PTR and A records with a TTL of zero will be added to a nameserver for the duration of the connection. When the connection is broken, PTR and A records will be removed, leaving only an MX record.
