Hi Anthony,

strongSwan doesn't resolve hostnames itself but uses getaddrinfo(3).  So it depends on how resolvers are configured on the local machine (and the abilities of the involved resolver(s)).  And when using CRLs and OCSP it depends on the fetcher plugin and the external library it uses (e.g.
libcurl) how the respective hostnames are resolved (might also be getaddrinfo, though).
