 # CheckMyIP - [myip.bsd.cafe](https://myip.bsd.cafe)
 
-A Telnet, SSH and Simple HTTP Based Public IP Address Lookup Service
+A Telnet, SSH, DNS and Simple HTTP Based Public IP Address Lookup Service
 
 
 -----------------------------------------
 
 ### USAGE
 
--   **TELNET**:
+#### DNS
-    -   Default: `telnet myip.bsd.cafe`
+- **DNS TXT Record**:
-    -   IPv4: `telnet myip4.bsd.cafe`
+  - Retrieve your IP via a DNS TXT record: `dig +short myip.bsd.cafe TXT @myip.bsd.cafe`
-    -   IPv6: `telnet myip6.bsd.cafe`
+
--   **SSH**:
+#### Telnet
-    -   Default: `ssh myip.bsd.cafe`
+- **Default**: `telnet myip.bsd.cafe`
-    -   IPv4: `ssh myip4.bsd.cafe`
+- **IPv4**: `telnet myip4.bsd.cafe`
-    -   IPv6: `ssh myip6.bsd.cafe`
+- **IPv6**: `telnet myip6.bsd.cafe`
-    -   Your SSH client may require you to enter a username. You can use anything you want (`ssh -l imrootbitch myip.bsd.cafe`)
+
--   **CURL**:
+#### SSH
-    -   Default: `curl -L myip.bsd.cafe`
+- **Default**: `ssh myip.bsd.cafe`
-    -   IPv4: `curl -L myip4.bsd.cafe`
+- **IPv4**: `ssh myip4.bsd.cafe`
-    -   IPv6: `curl -L myip6.bsd.cafe`
+- **IPv6**: `ssh myip6.bsd.cafe`
--   **WGET**:
+- Your SSH client may require you to enter a username. You can use anything you want (`ssh -l username myip.bsd.cafe`)
-    -   Default: `wget -qO- myip.bsd.cafe`
+
-    -   IPv4: `wget -qO- myip4.bsd.cafe`
+#### CURL
-    -   IPv6: `wget -qO- myip6.bsd.cafe`
+- **Default**: `curl -L myip.bsd.cafe`
+- **IPv4**: `curl -L myip4.bsd.cafe`
+- **IPv6**: `curl -L myip6.bsd.cafe`
+
+#### WGET
+- **Default**: `wget -qO- myip.bsd.cafe`
+- **IPv4**: `wget -qO- myip4.bsd.cafe`
+- **IPv6**: `wget -qO- myip6.bsd.cafe`
+
+For HTTP (CURL and WGET above), use `myip.bsd.cafe/raw` to get only the IP address. This also works for the HTTP IPv4 and IPv6 addresses.

------------------------------------------
-###   UPDATES IN V1.0.0 --> V1.1.0   ###
-
-**NEW FEATURES:**
-- Was seeing issues where SSH would be very slow to exchange. Likely related to log file sizes, so I change the logging function to turnover to new logging files every day.
-

-###   UPDATES IN V1.1.0 --> V1.3.0   ###
