iOS: Unable to resolve unicast DNS names that end in .local
iPad, iPhone, iPod touch
iOS devices may be unable to resolve unicast DNS names that end with a ".local" suffix, affecting access to internal corporate networks that use an internal, top-level domain name, such as "mydomain.local".
Changing your private network (if possible) to use a domain-name suffix other than ".local" will resolve this issue. When planning for internal corporate network naming, instead of ".local", use a domain suffix such as the following:
Bonjour's Multicast Domain Name Service (mDNS) uses the ".local" suffix to identify Bonjour-accessible devices. Avoiding use of a ".local" suffix when planning internal corporate networks is strongly recommended.
