| # Configuration for getaddrinfo(3). |
| # |
| # So far only configuration for the destination address sorting is needed. |
| # RFC 3484 governs the sorting. But the RFC also says that system |
| # administrators should be able to overwrite the defaults. This can be |
| # achieved here. |
| # |
| # All lines have an initial identifier specifying the option followed by |
| # up to two values. Information specified in this file replaces the |
| # default information. Complete absence of data of one kind causes the |
| # appropriate default information to be used. The supported commands include: |
| # |
| # reload <yes|no> |
| # If set to yes, each getaddrinfo(3) call will check whether this file |
| # changed and if necessary reload. This option should not really be |
| # used. There are possible runtime problems. The default is no. |
| # |
| # label <mask> <value> |
| # Add another rule to the RFC 3484 label table. See section 2.1 in |
| # RFC 3484. The default is: |
| # |
| #label ::1/128 0 |
| #label ::/0 1 |
| #label 2002::/16 2 |
| #label ::/96 3 |
| #label ::ffff:0:0/96 4 |
| #label fec0::/10 5 |
| #label fc00::/7 6 |
| #label 2001:0::/32 7 |
| # |
| # This default differs from the tables given in RFC 3484 by handling |
| # (now obsolete) site-local IPv6 addresses and Unique Local Addresses. |
| # The reason for this difference is that these addresses are never |
| # NATed while IPv4 site-local addresses most probably are. Given |
| # the precedence of IPv6 over IPv4 (see below) on machines having only |
| # site-local IPv4 and IPv6 addresses a lookup for a global address would |
| # see the IPv6 be preferred. The result is a long delay because the |
| # site-local IPv6 addresses cannot be used while the IPv4 address is |
| # (at least for the foreseeable future) NATed. We also treat Teredo |
| # tunnels special. |
| # |
| # precedence <mask> <value> |
| # Add another rule to the RFC 3484 precedence table. See section 2.1 |
| # and 10.3 in RFC 3484. The default is: |
| # |
| #precedence ::1/128 50 |
| #precedence ::/0 40 |
| #precedence 2002::/16 30 |
| #precedence ::/96 20 |
| #precedence ::ffff:0:0/96 10 |
| # |
| # For sites which prefer IPv4 connections change the last line to |
| # |
| #precedence ::ffff:0:0/96 100 |
| |
| # |
| # scopev4 <mask> <value> |
| # Add another rule to the RFC 6724 scope table for IPv4 addresses. |
| # By default the scope IDs described in section 3.2 in RFC 6724 are |
| # used. Changing these defaults should hardly ever be necessary. |
| # The defaults are equivalent to: |
| # |
| #scopev4 ::ffff:169.254.0.0/112 2 |
| #scopev4 ::ffff:127.0.0.0/104 2 |
| #scopev4 ::ffff:0.0.0.0/96 14 |
