+** socket, connect, accept etc., now have support for IPv6. IPv6 addresses
+ are represented in Scheme as integers with normal host byte ordering.
+
+** New function: inet-pton family address
+
+ Convert a printable string network address into an integer. Note
+ that unlike the C version of this function, the result is an
+ integer with normal host byte ordering. FAMILY can be `AF_INET'
+ or `AF_INET6'. e.g.,
+ (inet-pton AF_INET "127.0.0.1") => 2130706433
+ (inet-pton AF_INET6 "::1") => 1
+
+** New function: inet-ntop family address
+
+ Convert an integer network address into a printable string. Note
+ that unlike the C version of this function, the input is an
+ integer with normal host byte ordering. FAMILY can be `AF_INET'
+ or `AF_INET6'. e.g.,
+ (inet-ntop AF_INET 2130706433) => "127.0.0.1"
+ (inet-ntop AF_INET6 (- (expt 2 128) 1)) =>
+ ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff
