Returns true if the ipaddr is an IPv4-mapped IPv6 address.

Returns a new ipaddr built by converting the native IPv4 address into an IPv4-mapped IPv6 address.

Returns a string for DNS reverse lookup compatible with RFC1886.

Returns the wildcard mask in string format e.g. 0.0.255.255

Sets the date-time format.

Argument datetime_format should be either of these:

• A string suitable for use as a format for method Time#strftime.

• nil: the logger uses '%Y-%m-%dT%H:%M:%S.%6N'.

Returns the date-time format; see datetime_format=.

Creates an option from the given parameters params. See Parameters for New Options.

The block, if given, is the handler for the created option. When the option is encountered during command-line parsing, the block is called with the argument given for the option, if any. See Option Handlers.

Returns the sharing detection flag as a boolean value. It is false (nil) by default.

Sets the sharing detection flag to b.

Returns the length (in characters) of the matched substring corresponding to the given argument.

When non-negative argument n is given, returns the length of the matched substring for the nth match:

m = /(.)(.)(\d+)(\d)(\w)?/.match("THX1138.")
# => #<MatchData "HX1138" 1:"H" 2:"X" 3:"113" 4:"8" 5:nil>
m.match_length(0) # => 6
m.match_length(4) # => 1
m.match_length(5) # => nil

When string or symbol argument name is given, returns the length of the matched substring for the named match:

m = /(?<foo>.)(.)(?<bar>.+)/.match("hoge")
# => #<MatchData "hoge" foo:"h" bar:"ge">
m.match_length('foo') # => 1
m.match_length(:bar)  # => 2

Returns the substring of the target string from its beginning up to the first match in self (that is, self[0]); equivalent to regexp global variable $`:

m = /(.)(.)(\d+)(\d)/.match("THX1138.")
# => #<MatchData "HX1138" 1:"H" 2:"X" 3:"113" 4:"8">
m[0]        # => "HX1138"
m.pre_match # => "T"

Related: MatchData#post_match.

Returns the substring of the target string from the end of the first match in self (that is, self[0]) to the end of the string; equivalent to regexp global variable $':

m = /(.)(.)(\d+)(\d)/.match("THX1138: The Movie")
# => #<MatchData "HX1138" 1:"H" 2:"X" 3:"113" 4:"8">
m[0]         # => "HX1138"
m.post_match # => ": The Movie"\
