I am switching ISPs and no longer want to continue changing my internal webserver/etc to new IP addresses my ISPs provide.

How can I easily get a block of 10+ IPs from or someone else without paying a lot ?

    You can't.  IPv4 addresses have all been allocated.  The only thing you can do now is rent (for lack of a better term) them from an ISP.

    It's largely true that private consumers cannot get their own IPv4 addresses.  If you have a business and can justify it, you may be able to get them to give you one.

    You are an end user of ISP.

    If you don't want to change your IP then you need:

    a. At least /24 = 256 IP ( Less than /24 Block is not acceptable by most provider for BGP )
    b. Your own ASN (Autonomous Number)

    ASN is needed for BGP routing. Because BGP allows you to update your internal IP worldwide not a matter you change your Provider/ISP.

    If you plan to have your own IP then contact ARIN. You have to pay for IP and ASN yearly.
