Is it a big deal to have your internal domain names accessible externally? Many (though not all) DNS server allow private IPs in DNS.
- ComputerGuru 7y agoIt means making my internal name sever accept recursive calls from the internet at large. You’re proposing degrading my network security for this.
- tbyehl 7y agoIt creates a vulnerability for external devices -- they're trying to communicate with myhost.mydomain.com but really they're talking to whatever device has the same IP address on the network they're attached to. Some DNS hosters disallow private IPs. Some public resolvers and consumer routers will filter out responses containing private IPs.
