TITLE : gethostbyname(), gethostbyaddr()
PLEASE NOTE: these two functions are superseded by getaddrinfo() and getnameinfo()! In particular, gethostbyname() doesn't work well with IPv6........

TITLE : gethostbyname(), gethostbyaddr()
These functions map back and forth between host names and IP addresses. For instance, if you have "www.example.com", you can use gethostbyname() to get its IP address and store it in a struct in_addr........

TITLE : gethostbyname(), gethostbyaddr()
gethostbyname() takes a string like "www.yahoo.com", and returns a struct hostent which contains tons of information, including the IP address. (Other information is the official host name, a list of aliases, the address type, the length of the addresses, and the list of addresses窶琶t's a general-purpose structure that's pretty easy to use for our specific purposes once you see how.).......

TITLE : gethostbyname(), gethostbyaddr()
gethostbyaddr() takes a struct in_addr or struct in6_addr and brings you up a corresponding host name (if there is one), so it's sort of the reverse of gethostbyname(). As for parameters, even though addr is a char*, you actually want to pass in a pointer to a struct in_addr. len should be sizeof(struct in_addr), and type should be AF_INET........

TITLE : simple gethostbyname example | paul schreiber
Here’s a simple example using gethostbyname() that emulates the host command. I wrote it to debug a DNS problem. (On the network I’m on right now, gethostbyname() returns a different answer than host and dig. It is overagressively caching other hostnames. i.e. paulloookup shrub.ca is returning 17.250.248.64, which is mail.mac.com (!).......

If you do a gethostbyname() and there is no trailing dot after a domainname that does not resolve, this domainname will ultimately be appended to the server-FQDN by nslookup........

On another note, it can be a pain (when iterating with while loops for example) that on failure gethostbyname() returns the hostname, rather than FALSE. You could wrap it in a simple user function, to "correct" this:.......

In PHP4 you can use gethostbyname() but I have found this unreliable when doing lookups on entries that return A records on the private network. PHP5 has a much better routine -- dns_get_record(). If you are stuck with PHP4 or don't want to upgrade you can use dig:.......
