ECN-4384 BIS support for IPv6 addressing on UNIX

Type of Change: Enhancement

Product: ACUCOBOL-GT

Module: Business Information Server

New Version: 10.1.0

Machines Affected: UNIX

DESCRIPTION:

IPv6 addressing support has been added to the UNIX version of Xcentrisity Business Information Server (BIS) for extend. This will allow BIS to run in a network that uses IPv6 (128-bit) IP addresses. Largely, the Apache web server manages the IP addresses of the requests from clients, but there are two areas where BIS is affected:

• The {{Trace}} and {{Debug}} tags now accept IPv6 addresses, for the IP option, in the following forms:
  • x:x:x:x:x:x:x:x
  • x:x:x:x:x:x:d.d.d.d
  • d.d.d.d/p
  • x:x:x:x:x:x:x:x/p
  • x:x:x:x:x:x:d.d.d.d/p

  Where:

  d is a decimal numeric value, less that or equal to 255; x is a hexadecimal numeric value, less than or equal to 0xffff; p is a decimal value, less than or equal to 99.

  The special notation of two consecutive colons (::) indicates a sequence of multiple groups of 16-bit zeros. The :: can only appear once in an address. It can also be used to compress the leading and/or trailing zeros in an address.

  The /p format of the address specifies the prefix-length of the address. The prefix-length indicates the number of leftmost contiguous bits in the address that are valid.

• When a request is received from an IPv6 address, for licensing purposes, the address is interpreted as such:

  • An IPv6 address of fe80::/10 is considered a link local address.
  • An IPv6 address of fec0::/10 is considered a site local address.
  • A link or site local address is considered a private IP address.
  • An IPv6 address of ::1/128 is considered a loopback IP address.
