[Elecraft] K4 Remote Lives and Breathes!

[Rick Tavan]

Hi, Dave. I don't think it will be much of an issue. With many ISPs,
external IP addresses change rarely. If your ISP is changing addresses
frequently, consider using a DDNS server like no-ip.com. I have tested K4
Remote using a DDNS string in lieu of a hard-coded WAN address and it works
fine.
