My advice. Use the Cable Modem for DHCP IP address allocation. Just stopping it doing that job would be a major task in its own right with a Home Network setup. The same applies to DNS.
I am assuming that you are not running a Corporate Network (as distinct from a Home Network) and have not paid your ISP for a Fixed IP Address and control over the Cable Modem.

setdomainna
getdomainname(2) System Calls Manual getdomainname(2)
NAME
getdomainname, setdomainname - get or set name of current Network Information Service domain
SYNOPSIS
DESCRIPTION
returns the name of the Network Information Service (NIS) domain for the current processor, as previously set by The parameter namelen
specifies the size of the name array. The returned value is null-terminated unless the area pointed to by name is not large enough to hold
the domain name plus the null byte. In this case, only the namelen number of bytes is returned.
sets the domain of the host machine to name, which has a length of namelen. This call is restricted to the superuser and is normally used
only when the system is booted.
These Network Information Service domains enable two distinct networks with common host names to merge. Each network is distinguished by
having a different domain name. Currently, only the Network Information Service uses these domains.
RETURN VALUE
If the call succeeds, a value of 0 is returned. If the call fails, a value of -1 is returned and is set to indicate the error.
ERRORS
If or fail, is set to one of the following values:
name points outside the accessible address space.
The caller is not superuser.
This error only applies to
WARNINGS
The length of the name array should be at least 65; NIS domain names can be up to 64 characters long.
NIS servers use the NIS domain name as the name of a subdirectory of Since the NIS domain name can be as long as 64 characters, the domain
name set with can exceed the maximum file name length allowed on the local file system. If that length is exceeded, the name of the subdi-
rectory is the truncated NIS domain name.
