I hope noone shows him how ENUM works. Learning about a dns service that returns a regex (NAPTR, mapping & policy-based) so that you can rewrite your uri and query again (SRV), so that you can query again (A) could give him a heart attack - both because it's what DNS is not (apparently) and because it can be broken in 3 different ways by wildcards. In internal networks they're used quite often with a very low TTL for quick routing updates.
