In a domain name: \007 (RFC 1034 presentation encoding) In a host name: not possible as it is outside the allowable syntax. In a url it would depend upon the scheme. It would not be valid for http:, https: or mailto: to start with as all three are restricted to using hostnames. For those schemes where it is valid input %07.
