The usual URL to use the RentSportsEquip rental system is something like xyz.rentsportsequip.com. For Hotel Iso-Syöte located in Finland it’s hotelliisosyote.rentsportsequip.com. Of course they use a bookmark instead of having to type it every time but a much more comfortable and professional address is to use their own bhc.fi domain. The word rental in Finnish is vuokraamo. Hence their Internet address is simply vuokraamo.bhc.fi. Ask us to be able to use your own Internet domain to access your rentsportsequip.com site.
For you techies it means having your subdomain using CNAME to point to our/your rentsportsequip.com subdomain.
