+                        1. IPs are not allowed. Currently an IngressRuleValue can
+                        only apply to    the IP in the Spec of the parent Ingress.
+                        2. The `:` delimiter is not respected because ports are not
+                        allowed. \t  Currently the port of an Ingress is implicitly
+                        :80 for http and \t  :443 for https. Both these may change
+                        in the future. Incoming requests are matched against the host
+                        before the IngressRuleValue. If the host is unspecified, the
+                        Ingress routes all traffic based on the specified IngressRuleValue.

+                        wildcard label (e.g. \"*.foo.com\"). The wildcard character
+                        '*' must appear by itself as the first DNS label and matches
+                        only a single label. You cannot have a wildcard label by itself
+                        (e.g. Host == \"*\"). Requests will be matched against the
+                        Host field in the following way: 1. If Host is precise, the
+                        request matches this rule if the http host header is equal
+                        to Host. 2. If Host is a wildcard, then the request matches
+                        this rule if the http host header is to equal to the suffix

+                                  split by ''/''. Matching is   done on a path element
+                                  by element basis. A path element refers is the   list
+                                  of labels in the path split by the ''/'' separator.
+                                  A request is a   match for path p if every p is
+                                  an element-wise prefix of p of the   request path.
+                                  Note that if the last element of the path is a substring   of
+                                  the last element in request path, it is not a match
+                                  (e.g. /foo/bar   matches /foo/bar/baz, but does
+                                  not match /foo/barbaz). * ImplementationSpecific:
+                                  Interpretation of the Path matching is up to   the
+                                  IngressClass. Implementations can treat this as
+                                  a separate PathType   or treat it identically to
+                                  Prefix or Exact path types. Implementations are
+                                  required to support all path types.'
