    да не вопрос, понадобится несколько миллиардов долларов и помощь юристов чтобы выкупить свой личный блок адресов ,к примеру уровень 3 у IBM 9.0.0.0-9.255.255.255
    ну и вот еще в дополнение
    Code:
    Google Incorporated LVLT-GOOGL-1-8-8-8 (NET-8-8-8-0-1) 8.8.8.0 - 8.8.8.255

    Google Incorporated LVLT-GOOGL-1-8-8-4 (NET-8-8-4-0-1) 8.8.4.0 - 8.8.4.255

    Once these addresses have been registered as allocated out to another entity by Level3, Google can now advertise these addresses out of their infrastructure.

    There's a bit of magic that happens behind that which would take a bit of time to explain. The Internet works by having a lot of disparate networks from different entities connect together to form the global network that we call the Internet. They use a protocol called BGP to advertise that they either own a block of IP addresses or that they have a path to get to them. Other entities use this advertisement to know where to route stuff destined for those addresses.

    A lot of these entities (be it universities, companies, long-haul providers like telcos) also perform filtering of these advertisements as a way to keep entities honest about their advertisements. As an example, Joe Shmoe, Inc. couldn't advertise that they are the destination for Yahoo's network blocks because their upstream providers will only allow them to advertise the network blocks that are owned by Joe Shmoe, Inc.

    The Internet's routing architecture is actually a lot more precarious than most people realize. It's built on a lot of gentlemanly agreements and implicit trust. It does occasionally happen that someone is not performing correct route filtering on a customer link and the customer will, either acccidentally or maliciously, advertise that they are the destination for networks that they don't own. This can, and has, cause outages for people and systems that are logically close (from an Internet standpoint) to the malicious advertisement.

    Да, не я спросил потому что мне интересно было..По факту, цель была в случае чего делать редирект на дефолтный сайт с рекламой,
    для монетизации. Имхо, только сейчас понял, что это будет нерентабельно..Так как доступ к крупным рекламодателям почти невозможно получить.
