hi,
i set up an dns server.i seen that when i add or modify a new IP adress in zone file,i must restart dns server in order that the using nslookup to obtain the proper value.
is this a requirement to restart dns server after adding a new value?

It might be possible to just send the DNS server a signal to re-read the zone file. Depends on the server; BIND for example has the rndc command for this.

You could even write a DNS server that watches the zone file and reads it automatically when changes are detected.

Usually though, zones files are unlikely to change that often, so I guess it's ok to restart the server.

If you do a "restart" on your dns service then try a "reload" or "refresh" instead.
