strip carriage return & append next line
Hello everyone,
I am trying to search a file for lines that start with 'ip:' and have a carriage return after(ip:$). I then want to remove the carriage return from that line and append the next line in the file to the line containing 'ip'. I tried doing this with SED, but had no luck. Any assistance would be greatly appreciated.

COMMAND I TRIED(didnt work):
> sed 's/ip$/ip/g' <file_name>

## ORIGINAL FILE
Quote:
ip:
192.168.1.5
subnet: 255.255.255.0
ip: 192.168.1.5
subnet: 255.255.255.0
ip: 192.168.1.10
subnet: 255.255.255.0
ip:
192.168.1.55
subnet: 255.255.255.0
I want to make the file look like file below:

Quote:
ip: 192.168.1.5
subnet: 255.255.255.0
ip: 192.168.1.5
subnet: 255.255.255.0
ip: 192.168.1.10
subnet: 255.255.255.0
ip: 192.168.1.55
subnet: 255.255.255.0
