Using DNS ips I just go from dhcpcd in dhcpd?

I have dhcpd running. And it works fine. For the dns ips I just used two dns ips given to me by my isp. But I am at university, and when I go home for a week I bring my comp with me, along with my hub. So when I get home I have to change the dns ips to the ones of my parents ISP. My Question: Is there a way to get the dns IPs with dhcpcd (first run to get IP/ish from ISP) and then with the DNS servers I just got, give those to my dhcpd server?

dhcpcd will pick up the ISP supplied dns servers ok...

But are you using dhcpd as a full dns server for a domain, or just for caching?
There is an easier & more lightweight choice, dnsmasq which uses your resolv.conf & /etc/hosts files.
dhcpcd updates /etc/resolv.conf automatically

I made a script on my laptop. Haven't checked it out yet on my server, but will soon:

Code:

#!/bin/bash
cat /etc/dhcpd.conf.1st > /etc/dhcpd.conf
echo -n option routers\ \  >> /etc/dhcpd.conf
cat /etc/resolv.conf | cut -f 2 -d ' ' | grep -m 2 . | tr '\n' ',' >> /etc/dhcpd.conf
echo \; >> /etc/dhcpd.conf
cat /etc/dhcpd.conf.2nd >> /etc/dhcpd.conf

dhcpd.conf.1st and ".".2nd have the first and second part of my dhcpd.conf file in them. This is run before I run dhcpd eth1

I'll check out dnsmasq though.
