— Function: sockets:lookup-hostname host &key ipv6

Looks up a host by name or address. IPV6 determines the IPv6 behaviour, defaults to *IPV6*. Returns 4 values:

• an address
• a list of additional addresses(if existent)
• the canonical name of the host
• an alist of all the host's names with their respective addresses

— Function: sockets:ensure-hostname address &key ipv6 errorp

If address is an inet-address designator, it is converted, if necessary, to an inet-address object and returned. Otherwise it is assumed to be a host name which is then looked up in order to return its primary address as the first return value and the remaining address list as the second return value.

— Condition: sockets:resolver-error

Class precedence list: resolver-error, condition, t

— Condition: sockets:resolver-again-error

Class precedence list: resolver-again-error, resolver-error, condition, t

— Condition: sockets:resolver-fail-error

Class precedence list: resolver-fail-error, resolver-error, condition, t

— Condition: sockets:resolver-no-name-error

Class precedence list: resolver-no-name-error, resolver-error, condition, t

— Condition: sockets:resolver-unknown-error

Class precedence list: resolver-unknown-error, resolver-error, condition, t
