    Yeap you're right.

    If you want to avoid DNS based solutions, you should avoid the "isp link
    load balancing" appliances (like Radware LinkProof, F5 Link Controller,
    etc), as they are acting "like" bgp for outgoing communications, but use DNS
    tricks for incoming communications.

    I guess almost any serious isp/telco can provide you a internet line and
    configure some bgp to announce your addresses. If you want more information
    on bgp setup and the pre-requisites, feel free to contact me in private
    (we're near off-topic ;-)).

                    Best regards,
